This is what happens during election campaign. In our country, there are two weeks between the declaration of candidates and the polling of votes.

During this period the candidates contact their voters, political leaders address election meetings and political parties mobilise their supporters.

5. Election campaign often does not raise any basic questions and therefore does not offer any real voice to the people.

Question 47.
What is the importance of the independent Election Commission? How does such a commission help ensure free and fair elections?
Answer:
In our country, elections are conducted by an independent and very powerful Election Commission. A Commission enjoys the same kind of independence that the judiciary enjoys. The Chief Election Commissioner (CEC) is appointed by the President of India. But once appointed the Chief Election Commissioner is not answerable to the President or the government. Even if the ruling party or the government does not like what the Commission does, it is virtually impossible for it to remove the CEC.

The Election Commission is a very powerful body:

• Our Constitution gives it tire power to take decision on every aspect of conduct and control of elections from the declaration of elections to the declaration of results;
• The Commission lias the power to implement the Code of Conduct and punish any a candidates or party that violates it;
• During the period of the elections, the EC can order, the government to follow some guidelines, including transferring some government officials like the Collector or SP; and
• When government officers work on election duty, they are under the control of the EC and not the government.

Question 48.
Why are certain constituencies reserved and for whom?
Answer:
There are some constituencies which are reserved for people who belong to the Scheduled Castes [SC] and Scheduled Tribes (ST). In reserved (SC) constituency, only someone who belongs to the Scheduled Caste can stand for election. Similarly, only those belonging to Scheduled Tribe can contest. election from a reserved (ST) constituency.

The number of seats so reserved is in proportion to their population. Currently, in the Lok Sabha, 79 seats are reserved for the Scheduled Castes and 41 for the Scheduled Tribes. In the panchayat and Nagar Palika elections, one-third of the seats are reserved in a similar manner for women candidates. In many states, seats in panchayat and Nagar Palika are reserved for Other Backward Classes as well. This varies from state to state.

Why do we have this system? Isn’t this system unfair to those from other communities? It might seem so. But the gains of this system are much bigger. This system makes our democracy a representative democracy. If there were no system of reservation, very few persons from the Scheduled Castes and Scheduled Tribes would have been elected to the Lok Sabha and Vidhan Sabhas. They would not have had the resources. the education and conditions to contest elections against others.

They would have been discriminated against by others and prevented from winning elections. If that had happened, our parliament and assemblies would have been deprived of the voice of a significant section of our population. In any case the reserved seats do not take away the legitimate share of anyone else. The proportion of seats reserved for Scheduled Castes and Tribes is exactly in proportion to their share in population. In fact, inspired by the success of this system, women’s movement has been demanding a similar system for women as well.

Question 49.
Give a list of slogan raised during elections.
Answer:
In election campagins, political parties try to focus public attention on some big issues. They want to attract the public to that issue and get them to vote for their party on that basis. Let us look at some oi the successful slogans givne by different political parties in various elections.

Extra Questions for Class 9 Maths Chapter 10 Circles with Solutions Answers

Circles Class 9 Extra Questions Very Short Answer Type

Circles Class 9 Extra Questions Question 1.
In the figure, O is the centre of a circle passing through points A, B, C and D and ∠ADC = 120°. Find the value of x.

Solution:
Since ABCD is a cyclic quadrilateral
∠ADC + ∠ABC = 180°
[∴ opp. ∠s of a cyclic quad. are supplementary]
120° + ∠ABC = 180°
∠ABC = 180° – 120° = 60°
Now, ∠ACB = 90° [angle in a semicircle]
In rt. ∠ed ∆CB, ∠ACB = 90°
∠CAB + ∠ABC = 90°
x + 60° = 90°
x = 90° -60°
x = 30°

Class 9 Circles Extra Questions Question 2.
In the given figure, O is the centre of the circle, ∠AOB = 60° and CDB = 90°. Find ∠OBC.

Solution:
Since angle subtended at the centre by an arc is double the angle
subtended at the remaining part of the circle.
∴ ∠ACB = \(\frac{1}{3}\) ∠AOB = \(\frac{1}{3}\) x 60° = 30°
Now, in ACBD, by using angle sum property, we have
∠CBD + ∠BDC + ∠DCB = 180°
∠CBO + 90° + ∠ACB = 180°
[∵ ∠CBO = ∠CBD and ∠ACB = ∠DCB are the same ∠s]
∠CBO + 90° + 30° = 180°
∠CBO = 180o – 90° – 30° = 60°
or ∠OBC = 60°

Circles Extra Questions Class 9 Question 3.
In the given figure, O is the centre of the circle with chords AP and BP being produced to R and Q respectively. If ∠QPR = 35°, find the measure of ∠AOB.

Solution:
∠APB = ∠RPQ = 35° [vert. opp. ∠s]
Now, ∠AOB and ∠APB are angles subtended by an arc AB at centre and at the remaining part of the circle.
∴ ∠AOB = 2∠APB = 2 × 35° = 70°

Circle Class 9 Extra Questions Question 4.
In the figure, PQRS is a cyclic quadrilateral. Find the value of x.

Solution:
In ∆PRS, by using angle sum property, we have
∠PSR + ∠SRP + ∠RPS = 180°
∠PSR + 50° + 35o = 180°
∠PSR = 180° – 85o = 95°
Since PQRS is a cyclic quadrilateral
∴ ∠PSR + ∠PQR = 180°
[∵ opp. ∠s of a cyclic quad. are supplementary]
95° + x = 180°
x = 180° – 95°
x = 85°

Extra Questions Of Circles Class 9 Question 5.
In the given figure, ∠ACP = 40° and BPD = 120°, then find ∠CBD.

Solution:
∠BDP = ∠ACP = 40° [angle in same segment]
Now, in ∆BPD, we have
∠PBD + ∠BPD + ∠BDP = 180°
⇒ ∠PBD + 120° + 40° = 180°
⇒ ∠PBD = 180° – 160o = 20°
or ∠CBD = 20°

Extra Questions On Circles Class 9 Question 6.
In the given figure, if ∠BEC = 120°, ∠DCE = 25°, then find ∠BAC.

Solution:
∠BEC is exterior angle of ∆CDE.
∴ ∠CDE + ∠DCE = ∠BEC
⇒ ∠CDE + 25° = 120°
⇒ ∠CDE = 95°
Now, ∠BAC = ∠CDE [∵ angle in same segment are equal]
⇒ ∠BAC = 95°

Circles Class 9 Extra Questions Short Answer Type 1

Class 9 Maths Circles Extra Questions Question 1.
In the given figure, PQR = 100°, where P, Q and R are points on a circle with centre O. Find LOPR.

Solution:
Take any point A on the circumcircle of the circle.
Join AP and AR.
∵ APQR is a cyclic quadrilateral.
∴ ∠PAR + ∠PQR = 180° [sum of opposite angles of a cyclic quad. is 180°]
∠PAR + 100° = 180°
⇒ Since ∠POR and ∠PAR are the angles subtended by an arc PR at the centre of the circle and circumcircle of the circle.
∠POR = 2∠PAR = 2 x 80° = 160°
∴ In APOR, we have OP = OR [radii of same circle]
∠OPR = ∠ORP [angles opposite to equal sides]
Now, ∠POR + ∠OPR + ∠ORP = 180°
⇒ 160° + ∠OPR + ∠OPR = 180°
⇒ 2∠OPR = 20°
⇒ ∠OPR = 10°

Class 9 Maths Chapter 10 Extra Questions Question 2.
In figure, ABCD is a cyclic quadrilateral in which AB is extended to F and BE || DC. If ∠FBE = 20° and DAB = 95°, then find ∠ADC.

Solution:
Sum of opposite angles of a cyclic quadrilateral is 180°
∴ ∠DAB + ∠BCD = 180°
⇒ 95° + ∠BCD = 180°
⇒ ∠BCD = 180° – 95° = 85°
∵ BE || DC
∴ ∠CBE = ∠BCD = 85°[alternate interior angles]
∴ ∠CBF = CBE + ∠FBE = 85° + 20° = 105°
Now, ∠ABC + 2CBF = 180° [linear pair]
and ∠ABC + ∠ADC = 180° [opposite angles of cyclic quad.]
Thus, ∠ABC + ∠ADC = ∠ABC + 2CBF
⇒ ∠ADC = CBF
⇒ ∠ADC = 105° [∵ CBF = 105°]

Circles Class 9 Important Questions Question 3.
If the diagonals of a cyclic quadrilateral are diameters of the circle through the opposite vertices of the quadrilateral. Prove that the quadrilateral is a rectangle.
Solution:
Here, ABCD is a cyclic quadrilateral in which AC and BD are diameters.

Since AC is a diameter.
∴ ∠ABC = ∠ADC = 90°

In the given figure, AB and CD are two equal chords of a circle with centre O. OP and OQ are perpendiculars on chords AB and CD respectively. If ∠POQ = 120°, find ∠ APQ.

Solution: Since
AB = CD
∴ OP = OQ [∵ equal chords are equidistant from the centre]
∠OPQ = ∠OQP:
[by using isosceles triangle property, angles opp. to equal sides of a ∆]
In APOQ, by using angle sum property, we have
∠OPQ + ∠OQP + ∠POQ = 180°
⇒ ∠OPQ + ∠OPQ + 120° = 180°
⇒ 2∠0PQ = 60°
⇒ ∠OPO = 30°
Now, ∠APQ + ∠OPQ = 90°

∴ ∠B + ∠E = 180° …(i)
ABCD is a parallelogram.
∴ ∠B = ∠1 … (ii)
Also, ∠1 + ∠2 = 180° [linear pair]
∠B + ∠2 = 180° …(iii) [using (ii)]
Now, from (i) and (iii), we have

∠E = ∠2 In ∆DE, we have
∠E = ∠2

If two equal chords of a circle intersect within a circle, prove that the line segment joining the point of intersection to the centre makes equal angles with the chords.
Solution:

Join OP, draw OL ⊥ AB and OM ⊥ CD.
Thus, L and M are the mid-points of AB and CD respectively. Also, equal chords are equidistant from the centre.
∴ OL = OM
Now, in right-angled As OLP and OMP
OL = OM
OP = OP [common]
∠OLP = ∠OMP [each = 90°]
So, by RHS congruence axiom, we have
∆OLP ≅ ∆OMP

Const. : Join OP, OQ, O’P and O’Q
Proof : In ∆OPO’ and ∆OQO’
OP = OQ [radii of same circle]
OᏢ = QQ [radii of same circle]
OO’ = OO [common]
⇒ ∆OPO’ ≅ ∆OQO’ [by SSS congruence axiom]
⇒ ∠POM = ∠QOM [c.p.c.t.]
Now, in ∆POM and ∆QOM
OP = OQ
(radii of same circle]
∠POM = ∠OOM [proved above]
OM = OM [common]
∆POM ≅ ∆QOM [by SAS congruence axiom]
PM = QM and ∠PMO = ∠QMO [c.p.c.t.]
Also, ∠PMO+ ∠QMO = 180° [linear pair]
⇒ ∠PMO = ∠QMO = 90°

Circles Class 9 Extra Questions Long Answer Type

Question 1.
In the given figure, O is the centre of a circle of radius r сm, OP and OQ are perpendiculars to AB and CD respectively and PQ = 1cm. If AB || CD, AB = 6cm and CD = 8cm, determine r.

Solution:
Since the perpendicular drawn from the centre of the circle to a chord bisects the chord. Therefore, P and Q are mid-points of AB and CD respectively.
Consequently, AP = BP = \(\frac{1}{2}\)AB = 3 cm
and CQ = QD = \(\frac{1}{2}\)CD = 4 cm
In right-angled AQAP, we have
OA² = OP² + AP²
r² = OP² + 3²
r² = OP² + 9
In right-angled ∆OCQ, we have
OC² = OQ² + CQ²
r² = OQ² + 4²
p² = OQ² + 16 … (ii)
From (i) and (ii), we have
OP² + 9 = OQ² + 16
OP² – OQ² = 16 – 9
x² – (x – 1)² = 16 -9 [where OP = x and PQ = 1 cm given]
x² – y² – 1 + 2x = 7
2x = 7 + 1
x = 4
⇒ OP = 4 cm
From (i), we have
r² = (4)² + 9
r² = 16 + 9 = 25
r = 5 cm

Question 2.
In a circle of radius 5 cm, AB and AC are two chords such that AB = AC = 6 cm, as shown in the figure. Find the length of the chord BC.

Solution:
Here, OA = OB = 5 cm [radii]
AB = AC = 6 cm
∴ B and C are equidistant from A.
∴ AO is the perpendicular bisector of chord BC and it intersect BC in M.
Now, in rt. ∠ed ∆AMB, M = 90° ….(i)
∴ By using Pythagoras Theorem, we have
BM² = AB² – AM²
= 36 – AM²
Also, in rt. ∠ed ∆BMO, ∠M = 90°
∴ By using Pythagoras Theorem, we have
BM² = BO² – MO² = 25 – (AO – AM)²
From (i) and (ii), we obtain
25 – (AO – AM)² = 36 – AM\(\frac{1}{2}\)
25 – AOC – AM² + 240 × AM = 36 – AM\(\frac{1}{2}\)
25 – 25 + 2 × 5 × AM = 36
10 AM = 36
AM = 3.6 cm
From (i), we have
BM² = 36 – (3.6)² = 36 – 12.96 = 23.04
BM = √23.04 = 4.8 cm
Thus, BC = 2 × BM
= 2 × 4.8 = 9.6 cm
Hence, the length of the chord BC is 9.6 cm.

Question 3.
In the given figure, AC is a diameter of the circle with centre O. Chord BD is perpendicular to AC. Write down the measures of angles a, b, c and d in terms of x.

Solution:
Here, AC is a diameter of the circle.
∴ ∠ADC = 90°
⇒ ∠a + ∠d = 90°
In right-angled ∆AED, ∠E = 90°
∴ ∠a + 2b = 90°
From (i) and (ii), we obtain
∠b = ∠d ….(iii)
Also, ∠a = ∠c … (iv)
[∠s subtended by the same segment are equal]
Now, ∠AOB and ∠ADB are angles subtended by an arc AB at the centre and at the remaining part of the circle.

Question 4.
Show that the quadrilateral formed by angle bisectors of a cyclic quadrilateral is also cyclic.

Solution:
Given : A cyclic quadrilateral ABCD in which AP, BP, CR and DR are the angle bisectors of ∠A, ∠B, 2C and ∠D respectively such that a quadrilateral PQRS is formed. To Prove: PQRS is a cyclic quadrilateral.
Proof : Since ABCD is a cyclic quadrilateral.
∴ ∠A + 2C = 180° and ∠B + ∠D = 180°
Also, AP, BP, CR and DR are the angle bisectors of ∠A, ∠B, ∠C and ∠D respectively.

or ∠1 + ∠3 = 90°
and ∠2 + ∠4 = 90°
Now, in ∆APB, by angle sum property of a ∆
∠1 + ∠2 + ∠P = 180° … (iii)
Again, in ∆CRD, by angle sum property of a ∆
∠3 + ∠4 + ∠R = 180° …(iv)
Adding (iii) and (iv), we have
∠1 + ∠2 + ∠3 + ∠4 + ∠P + ∠R = 180° + 180°
90° + 90° + ∠P + ∠R = 360° [using (ii)]
∠P + ∠R= 360° – 180° = 180°
i.e., the sum of one pair of the opposite angles of quadrilateral PQRS is 180°.
Hence, the quadrilateral PQRS is a cyclic quadrilateral.

Solution:
In circle Clo, r), PQ and PR are two chords, draw OM I PQ, OL I PR, such that OM = a

Solution:

Let ∠BAD = x, ∠ABE = y
and ∠ACF = 2, then
∠CAD = x, ∠CBE = y
and ∠BCF = 2 [AD, BE and CF is bisector of ∠A, ∠B and ∠C]
In ∆BC,
∠A + ∠B + ∠C = 180°
⇒ 2x + 2y + 2Z = 180°
or x + y + Z = 90° …(i)
Now, ∠ADE = ∠ABE
and ∠ADF = ∠ACF [angles in the same segment of a circle]
⇒ ∠ADE = y and ∠ADF = Z
⇒ ∠ADE + ∠ADF = y + Z
or ∠D = y + Z …(ii)
From (i) and (ii), we have
x + 2D = 90°
⇒ ∠D = 90° – x

Question 1.
A small cottage industry employing people from a nearby slum area prepares round table cloths having six equal designs in the six segment formed by equal chords AB, BC, CD, DE, EF and FA. If O is the centre of round table cloth (see figure). Find ∠AOB, ∠AEB and ∠AFB. What value is depicted through this question ?

Solution:
Since six equal designs in the six segment formed by equal chords AB, BC, CD, DE, EF and FA.
Therefore, we have six equilateral triangles as shown in the figure. Since ∆AOB, ∆BOC, ∆COD, ∆DOE, ∆EOF
∴ Each angle is equal to 60°.

∠AOB = 60°
∠AOB, ∠AEB and ∠AFB are angles subtended by an arc AB at the FK centre and at the remaining part of the circle.
∴ ∠AEB = ∠AFB = \(\frac{1}{2}\) ∠AOB = \(\frac{1}{2}\) × 60° = 30°
Thus, ∠AEB = ∠AFB = 30°
Value depicted : By employing people from a slum area to prepare round table clothes reali∠e their social responsibility to work for helping the ones in need.

Question 1.
The velocity of a body moving in a straight line is inereásed by applying constant force F, for some distance in the direction of motion. Prove that the increase ¡n the kinetic energy of the body is equal to the work done by the force on the body.
Answer:
Let us consider an object lying on a frictionless surface having mass ‘m’.

A force of constant magnitude ‘F’ is acting on the body. Here initial velocity of the body is u and the final velocity is u. As there is no dissipative forces, work on the body will be stored in the form of a change in kinetic energy. It can be proved as
W = Fs …………(1)
and hence from the equation of motion
υ² – u² = 2as
s = \(\frac{v^{2}-u^{2}}{2 a}\) ………….(2)
Asweknowthat F = ma
Using (1), (2) and (3),
W = ma x \(\frac{v^{2}-u^{2}}{2 a}\)
= \(\frac {1}{2}\) m (υ² – u²)
= \(\frac {1}{2}\)mυ² – \(\frac {1}{2}\)mu²
= change in kinetic energy

Question 2.
Derive an expression for potential energy. Write Its SI unit.
Answer:
When work is done on the body, the work is stored in the form of energy. Consider an object of mass, m. Let it be raised through a height, h from the ground. A force is required to do this. The minimum force required to raise the object is equal to the weight of the object, mg. The object gains energy equal to the work done on it. Let the work done on the object against gravity h be W.
i.e., W = force x displacement = mgh

Since work done on the object is equal to mgh, an energy equal to mgh units is gained by the object. This is the potential energy (E_p) of the object.
∴ E_p = mgh
SI unit of potential energy is the joule (J).

Question 1.
State the conditions for positive, negative, and zero work. Give at least one example of each.
Answer:
1. Zero work: If the angle between force and displacement is 90°, then work done is said to be zero work.
Example: When a man carries a load on his head and moves on a level road. Work done by the man on the load is zero.

2. Positive work: Work done is said to be positive if the force applied on an object and displacement are in the same direction.
W = Fs

Example: Work done by the force of gravity on a falling body is positive.
3. Negative work: Work done is said to be negative if the applied force on an object and displacement is in opposite direction.
W = -Fs
Her displacement is taken to be negative (- s).

Example: Work done by friction force applied is negative on a moving body.

Question 2.
Give a reason for the following:
(a) A bullet is released on firing the pistol.
(b) An arrow moves forward when released from the stretched bow.
(c) Winding the spring of a toy car makes it to run on the ground.
(d) Falling water from a dam generates electricity.
(e) Winding the spring of our watch, the hands of the watch movement.
Answer:
(a) The chemical energy of gun powder is converted into kinetic energy of the bullet.
(b) The elastic potential energy in a stretched bow is converted into kinetic energy of the arrow.
(c) The potential energy of a spring is converted into kinetic energy of the toy.
(d) The kinetic energy of water is converted into electric energy.
(e) The potential energy of spring due to its windings is converted into mechanical energy of the watch.

Question 3.
State the law of conservation of energy. Show that the energy of a freely falling body is conserved.
Answer:
Energy can neither be created nor be destroyed, it can only be transformed ‘ m A from one form to another. The total energy before and after the transformation always remains constant.
Let us consider an object of mass ‘m’ dropped from a height h.
Total energy at point A

\(E_{T_{A}}=E_{K}+E_{P}\)
or, \(E_{T_{A}}=0+m g h\)
∴ \(E_{T_{A}}=m g h\)
Total energy at point B,
\(E_{T_{B}}=E_{T}+E_{p}\)
For finding out velocity at point B
apply υ² – u² = 2as
\(v_{\mathrm{B}}^{2}=2 g h\) = 2gh
Hence, \(E_{T_{B}}=\frac{1}{2} m \mathrm{V}_{\mathrm{B}}^{2}+m g\)
\(E_{T_{B}}=\frac{1}{2} m(2 g h)=m g h\)
Here, \(E_{T_{A}}=E_{T_{B}}\)
Hence if there is no energy loss, total energy is conserved.

Question 1.
A running man has half the kinetic energy that a body of half of his mass has. The man speeds up by 1 m/s and then has the same kinetic energy as the boy. What are the original speeds of the man and the boy?
Answer:
Let us take
mass of boy = m
mass of man = M
velocity of boy = u
velocity of man = υ
Here, m = \(\frac {M}{2}\)
Initially
E_Kof man = \(\frac {1}{2}\) E_K of boy
\(\frac {1}{2}\) Mυ² = \(\frac {1}{2}\) mu² x \(\frac {1}{2}\)
and \(\frac {1}{2}\) Mυ² = \(\frac {1}{2}\) \(\frac{1}{2}\left(\frac{M}{2}\right) u^{2} \times \frac{1}{2}\)
∴ υ² = \(\frac{u^{2}}{4}\) ………….(1)

Finally
E_K of man = E_K of boy
\(\frac {1}{2}\)M(υ +1)² = \(\frac {1}{2}\) mu²
\(\frac {1}{2}\)M(υ +1)² = \(\frac{1}{2}\left(\frac{M}{2}\right) u^{2}\)
(υ +1)² = \(\frac{u^{2}}{2}\)
∴ υ +1 = \(\frac{u}{\sqrt{2}}\) …………(2)
υ = \({\sqrt{2}}\) + 1 = 2.41 m/s
and u = 4.82 m/s

Question 2.

Answer:
1. Power is rate of doing work.
2. Kilowatt is the unit of power and kilowatt-hour is unit of energy.
3. Given, height, h = 20 m
Mass per unit time,
m/t = 2000 tonnes per minutes = \(\frac{2000 \times 10^{3}}{60}\) kg/s
Power P = \(\frac{W}{t}=\frac{m g h}{t}=\frac{2000 \times 10^{3}}{60}\) = 10 x 20
∴ P = 6.67 x 10⁶ W = 6.67 MW

Question 7.
What happens to the kinetic energy when:
1.  the mass of the body is doubled at constant velocity?
2. the velocity of the body is doubled at constant mass?
3. the mass of the body is doubled but velocity is reduced to one fourth?
Answer:
1. The kinetic energy of body is given by,
E_k = \(\frac {1}{2}\) mυ⁶, E_k ∝ m. If the mass of the body is doubled its kinetic energy is also doubled.

2. Kinetic energy, E_k ∝ u²
If velocity of the body is doubled, its kinetic energy becomes four times.

3. Initial kinetic energy,
\(E_{K_{i}}\)= \(\frac {1}{2}\) mu²
Final kinetic energy,
\(E_{K_{f}}\) = \(\frac {1}{2}\)(2m) \(\left(\frac{v}{4}\right)^{2}=\frac{m v^{2}}{16}\)
Kinetic Energy becomes one eighth.

Question 8.

Answer:
Given,
Mass of the Sun, M = 2 x 10³⁰ kg
Mass of the Earth, m = 6 x 10²⁴ kg
Distance between the Sun and the Earth,
r = 1.5 x 10¹¹ m
Gravitational force between two masses is given by,
F = \(\frac{\mathrm{GMm}}{r^{2}}\)

∴ F = 3.6 x 10²²N

Question 2.
A planet x has a mass 2 times and radius 3 times that of the Earth. What is the acceleration due to gravity on the planet, if the acceleration due to gravity on the Earth is 10 m/s².
Answer:
Given, Mass of planet, M_p = 2 M_e
Radius of planet,
Acceleration due to gravity of Earth,g_e = \(\frac{G M_{e}}{R_{e}^{2}}\) ………(i)
Acceleration due to gravity of planet,g_p = \(\frac{\mathrm{GM}_{p}}{r_{p}^{2}}=\frac{\mathrm{G} \times 2 \mathrm{M}_{e}}{\left(3 \mathrm{R}_{e}\right)^{2}}\)
or, g_p = \(\frac{2 \mathrm{GMe}}{9 \mathrm{R}_{e}^{2}}\)
∴ g_p = \(\frac {2}{9} \) g_e
∴ g_p = 2.22 m/s²

Question 1.
State following laws or principles
(a) Newton’s law of gravitation
(b) Pascal’s law
(c) Archimede’s principle
Answer:
Newton’s law of gravitation: Every particle in the universe attracts every other particle with a force, which is directly proportional to the product of their masses and inversely proportional to the square of distance between the two masses.

Pascal’s law: In an enclosed fluid, if pressure is changed in any part of the fluid, then this change in pressure is transmitted undiminished to all the other parts of the fluid.

Archimede’s principle: When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it.

Question 2.
Calculate the average density of the Earth in terms of g, G, and R.

Acceleration due to gravity at the surface of the Earth is given by, g = \(\frac{\mathrm{GM}}{r^{2}}\)
If the Earth is considered to be a perfect sphere, mass of Earth, M = dυ = d x \(\frac{4}{3}\)πr³
Putting value of mass in above formula g.
g = \(\frac{G \times d \times \frac{4}{3} \pi r^{3}}{r^{2}}\)
or, g = \(\frac{4}{3}\) πd GR
∴ d = \(\frac{3g}{4tGR}\)
Here, d = average density of the Earth
g = acceleration due to gravity
G = universal gravitational constant.

Question 3.

From (1) and (2),
\(g =\frac{G M}{r^{2}}\)

Question 4.
Why does an object float or sink when placed on the surface of the water?
Answer:
When an object is placed on the surface of the water, two forces act on the object.

• The gravitational force in the downward direction.
• Upthrust or buoyant force in the upward direction.

When the gravitational force is greater than the upthrust or buoyant force on the object, the object sinks in water. if the upthrust or buoyant force is greater than or equal to the gravitational force, then the object floats.
Or
if the average density of the object is greater than the density of water, the object sinks. If the average density of the object is less than or equal to the density of water, the object floats.

(n) Why do skiers use flat skies to slide over snow?
(o) Why are broad handles provided in bags and suitcases?
(p) Why a camel walks easily on the sandy surface than a man?
(q) Why is it easier to swim in seawater than ordinary river water?
(r) Why does a ship made of iron float on the water while a nail made of iron sink into water?
(s) Why does an object experience more buoyant force on the Earth than on the moon?
(t) Why is it easy to lift a heavy stone underwater?
(u) Why are cutting and piercing tools made sharp?
Answer:
(a) Since the acceleration due to gravity at the equator is less than the acceleration due to gravity at the poles. So the weight of the body is less at the equator than at the poles.
(b) When we move away from the center of Earth, acceleration due to gravity decreases (above the surface of Earth). So the weight of the object at the mountain is less in comparison to the weight at the surface.
(c) The value of acceleration due to gravity at the surface of the moon is one-sixth times the value of acceleration due to gravity at the surface of the Earth. So the weight of a body on the moon is one-sixth times the weight of the body on the Earth.
(d) Acceleration due to gravity at the center of the Earth is zero. Hence the weight of the object is zero.
(e) The density of an iron nail is greater than the density of water so, it sinks in water. The density of a wooden cork is less than the density of water, hence it floats on water.
Or
The weight of an iron nail is greater than the upthrust or buoyant force on the iron nail, so it sinks in water. On the other hand upthrust or buoyant force on the cork is equal to the weight of the cork. Hence the wooden cork floats on water.
(f) The density of hydrogen is less than the density of air.
Or
The upthrust on buoyant force acting on a hydrogen balloon is greater than the weight of the hydrogen balloon. So it floats in air.
(g) A bucket of water appears lighter inside water due to the upthrust or buoyant force of water.
(h) The pressure is inversely proportional to the area for the same force. Therefore pressure exerted by a sharp knife îs more than the pressure exerted by a blunt knife. Therefore, a sharp knife is more effective in cutting an object than a blunt knife.
(i) Due to the upthrust or buoyant force of a water, we feel light.
(j) 8y using a wide tire, the area of contact with the ground is increased and hence the load is distributed
on a larger area to reduce pressure.
(k) Nails and pins have pointed ends so that these can be fixed with minimum force because the pressure on the pointed ends would be large.
(l) Wide wooden sleepers are kept below railway lines to reduce pressure on the railway tracks and prevent them from sinking into the ground.
(m) The foundation of a building or a dam has a large surface area so that the pressure exerted on the ground is less. This is done to prevent the sinking of the building or dam into the ground.
(n) To increase surface area and decrease pressure on snow.
(o) Using broad handles increases area and hence decreases pressure.
(p) A camel walks easily on the sandy surface because the area of the camel’s feet is large as compared to the area of a man’s feet. So the pressure exerted by the camel on the sandy surface is very small as compared to the pressure exerted by the man. Therefore the feet of the camel do not sink much in the sand due to small pressure.
(q) The density of seawater is greater than the density of river water. Upthrust or buoyant force acting on a body is more in seawater.
(r) An iron nail sinks in water because the density of iron is greater than that of water. So the weight of the nail is more than the upthrust of water on it. On the other hand, a ship made of iron does not sink. This is because the ship is hollow and the empty space contains air which makes the average density of the ship less than that of water and hence it floats.
(s) The buoyant force acting on a body depends on acceleration due to gravity. Acceleration due to gravity on the Earth is more than that on the moon.
(t) When a stone is placed in water, an upthrust or buoyant force acts on it due to which its apparent weight or net downward force on it decreases.
(u) To exert more pressure with the same force as pressure is inversely proportional to area. With increasing sharpness area decreases and hence pressure increases.

Question 19.
Do you think George and Harris were experts at packing? Give reasons for your answer.
Answer:
No, George and Harris do not seem to have been experts, because they started by breaking a cup, and continued by squashing a tomato under the bottle of jam.

George and Harris were, in fact, much worse than Jerome as they set about packing. They fumbled and blundered many times while packing the hamper.

They jumbled up the items to be packed and crushed softer things like pies under heavy objects.

Answer:
Montmorency was the pet dog of the narrator and his two friends. He made a complete nuisance of himself. He sat down on things which had to be packed, pushed his nose into Harris or George’s hand whenever they reached out for anything, put his leg into the jam, played with a teaspoon and pretended the lemons were rats. He chased the lemons inside the hamper till he ‘killed’ three of them, before he was hit by Harris with a frying pan.

Question 23.
What was the ‘highest aim and object’ of Montmorency, according to the narrator?

According to the narrator, Montmorency’s highest aim and object was to get in people’s way and make them stumble over him. He aspired to get cursed by everyone and liked things to be thrown at him for his unbearable interference.

Answer:
According to the narrator, he was the best packer in the world while George and Harris were the worst. I agree with him when he says he is better in packing as he packs the bag neatly and seriously while his friends pack the hampers carelessly while laughing, playing, fighting and breaking things.

Question 26.

Harris blamed Jerome for encouraging Montmorency because Jerome did not prove effective in shooing away the dog. Jerome’s defence was that an ill-trained dog like Montmorency did not need any encouragement to misbehave. Indiscipline came naturally to him.

Packing Extra Questions and Answers Long Answer Type

Question 1.
Who offered to pick the bag for the trip? Was he happy at his own offer
Answer:
The author and his friends decided to go on a holiday. The author, who saw himself as an expert in packing. “I rather pride myself on my packing. Packing is one of those many things that I feel I know more about than any other person living.” He told his friends, George and Harris that he would do the packing.

They readily agreed to his suggestion. George sat in an easy chair, while Harris put his legs on a table. The author had not intended this. He was unhappy with himself for having offered to pack. He had thought that Harris and George would pack and he would supervise them, teaching them how to do things better. When he worked and his friends relaxed, he was greatly irritated.

Question 2.
Briefly describe Jerome’s attempt at packing.
Answer:
Right in the beginning Jerome volunteered to pack, because, according to him, he was especially good at it and George and Harris agreed readily. What Jerome of course had meant was that he would supervise the packing while they packed. They of course meant he’d pack while they watched from lounging positions. Jerome packed all their personal belongings, from boots to toothbrushes. When he had finished, Harris pointed out whether he wanted to leave the boots out.

Once the boots were packed, Jerome realised he needed his toothbrush out for the morning, so the entire bag had to be unpacked and the toothbrush searched. It was found in a boot. The bag was again repacked when Jerome discovered he had packed his spectacles in. Once again, the bag was unpacked to take out the spectacles and then repacked. After going through several unpleasant rounds of unpack, repack, unpack, repack, the job was done, with only the soap (possibly) having been forgotten.

Question 3.
How did George and Harris fare with the packing of the hamper?
Answer:
After Jerome’s display of expert packing, George and Harris thought that, they’d better pack the foods and supplies. They had the “big hamper” to pack with these items. They started by breaking a cup, then squashing tomatoes with the jam. Then they packed the pies and “smashed the pies in” with heavy things on top. They spilled salt everywhere then, in turns, stepped on the butter, tried to cram it into the kettle, sat on the butter, hunted for the now missing butter (until George got a back view of Harris), and finally shoved it into the teapot.

Montmorency played his role during the packing incident by assuming his cold nose was what Harris’s and George’s hands were reaching for. He sat on the very item that was to be packed next, upset the spoons, put his leg into the jam and attacked the lemons in the hamper. Once the hamper was packed and closed, Harris sat on the lid of the hamper, and said he hoped nothing . “would be found broken,” to which George replied that “if anything was broken it was broken.”

Question 4.
Of the three, Jerome, George and Harris, who do you think is the best or the worst packer? Support your answer with details from the text.
Answer:
According to me, Jerome is the best in packing. Although Jerome, George and Harris are equally disorganised as packers, Jerome is not as clumsy as his two friends, Harris and George. While Jerome takes a lot of time to pack the bag, George and Harris damage a lot of things while packing the hamper. Jerome, who considers himself a skilled packer, is able to arrange the items to be packed in the bag neatly and in order.

However, there is a lot of delay because he first forgets to pack his boots and then forgets having packed his toothbrush. After unpacking twice, he again packs in his spectacles absentmindedly. On the other hand, both Harris and George messed up everything. They began by breaking a cup.

Then, Harris packed the strawberry jam on top of a tomato and squashed it. George stepped on the butter, then Harris sat on it. They spread salt all over the place. Of course, Montmorency constantly got in their way and made things worse. Once the hamper was packed and closed, Harris sat on the lid of the hamper, and said he hoped nothing “would be found broken,” to which George replied that “if anything was broken it was broken.” Thus, we can easily conclude that though Jerome and George and Harris bungled equally. However, Jerome did not cause as much breakage or chaos as George and Harris.

Question 5.
How did the butter episode in the story cause nuisance?
Answer:
The butter episode in the story caused a lot of nuisance as it brought out the bungling clumsiness of George and Harris. First of all, George stepped on the butter and it stuck to his slipper. After George had got it off his slipper, he and Harris tried to put it in the kettle. It wouldn’t go in, and what was in wouldn’t come out. They d narrator id scrape it out at last, and put it down on a chair. Then Harris sat on it, and it stuck to him, and they went looking for it all over the room.

“I’ll take my oath I put it down on that chair,” said George, staring at the empty seat. George finally noticed it behind Harris’s back from where it was removed and put inside the teapot. Hence, the butter episode created a lot of nuisance and became the funniest episode in the story.

Question 6.
Do you find this story funny? What are the humorous elements in it?
Answer:
The story is very funny with dry and slapstick humour. The chaos and confusion created by all the characters is very amusing. The gap between the self-assessment of Jerome, George and Harris and their actual capabilities is highly entertaining. Montmorency’s contribution to humour is no less significant.

Jerome’s sense of pride about his packing skills and the manner in which he packs the bag is very funny. He claims, “I rather pride myself on my packing. Packing is one of those many things that I feel I know more about than any other person living.” While Jerome expected to use the opportunity for bossing over his friends, of “pushing them aside every now and then with, “Oh, you!” “Here, let me do it.” “There you are, simple enough!” — really teaching them, as you might say.” They make him toil instead, lounging about and offering helpful suggestions. Jerome’s forgetfulness and the subsequent unpacking of the bag many times over is quite amusing.

The butter episode, in particular, generates a lot of laughter. First of all, George stepps on the butter and it sticks to his slipper. After George has got it off his slipper, he and Harris try to unsuccessfully put it in the kettle. They put it down on a chair and then Harris sits on it, and it sticks to him, and they go looking for it all over the room. George finally noticed it behind Harris’s back from where it is removed. Montmorency, the dog, too adds to the humour with his habit of getting in the way of things. His indiscipline and inquisitiveness earns him curses but he still manages to put his leg in the jam and chase lemons like rats till he is hit by Harris with a frying pan. All these instances lend humour to the story.

Question 7.
When did the “horrible idea” occur to Jerome? Why was it a “horrible idea”?
Answer:
The “horrible idea” that occurred to Jerome as soon as he had finished packing in his boots was whether he had packed in his toothbrush or not. He often forgot to pack his toothbrush, or, would pack it at night before using it in the morning. This would haunt him so much that at night he would dream that he had not packed the toothbrush. He would wake up in a cold sweat, get out of bed and hunt for it and pack it without using it in the morning, which meant that he would have to unpack it again.

And whenever he was looking for it, it would be the last thing to come out of the bag. After using it he would again forget to pack it and at the last moment would have to rush upstairs to fetch it. As a result he would carry it to the railway station, wrapped up in his pocket-handkerchief. Thus, the toothbrush was a constant source of horrible nightmares for Jerome.

Mirror Extra Questions and Answers Class 10 English Literature

Mirror Extra Questions and Answers Long Answer Type

Mirror Poem Questions And Answers Class 10 Question 1.
Why does the woman not like the mirror?
Answer:
This poem explores the relationship that we have with truth, and particularly the truth about ourselves. The mirror doesn’t tell lies—it, in fact, tells the truth. It is objective—‘exact’ and without ‘preconceptions’, swallowing whatever it sees without a second thought, ‘unmisted by love or dislike’. The mirror is, ‘not cruel, only truthful’ but Plath suggests that truth itself is cruel for human beings, and we turn away from it, presenting only our backs to those mirrors that offer to show it to us. The woman does not like the blemishes which the mirror shows her and turns away to ‘those liars, the candles or the moon.’

Mirror Questions And Answers Class 10 Question 2.
Why is the woman bending over the lake?
Answer:
The lake is something else into which humans have traditionally gazed, in search of their own reflection. The lake is not as exact as the mirror and hence the person who looks into it will get a flattering view of himself or herself as the reflection in the lake can be distorted by the ripples in the water. Though some of her imperfections are hidden by the water, here too the woman moves away as the depth of the lake reflects her repressed mind. She turns to more flattering devices like the candles and the moon.

The Mirror Questions And Answers Class 10  Question 3.
In the poem, The Mirror, the poet underlines the misery of an ageing woman when she sees her reflection in a mirror. What makes her hate the mirror?
Answer:
The woman looks into the mirror to see her reflection. But the mirror being objective shows her an image that she does not like. It shows her the flaws which have appeared on her face as she is ageing. Though the mirror is being ‘not cruel, only truthful’ but truth itself is cruel and the woman turns away from it, presenting her back to that unbiased truth. What value we can derive from these lines is that is that it takes courage to face the truth. The woman cannot live without knowing the reality even if it upsets her and so each morning the woman is back, even though it is only to cry and wring her hands at what she sees.

Mirror Question Answer Class 10 Question 4.
The mirror plays a significant role in the life of the woman. Discuss.
Answer:
The mirror is an object the woman has always turned to in search of truth, from childhood to the present, when she is ageing. It is objective and without ‘preconceptions’, swallowing whatever it sees without a second thought. The mirror in presenting reality is being ‘not cruel, only truthful’.

The value that can be derived from this is that truth itself is cruel for the woman who is agitated by the truth and turns away from it, presenting her back to the mirror. It does not intend to hurt the woman but truth is sometimes unintentionally cruel.

My Mirror Likes To Argue Poem Questions And Answers Class 10 Question 5.
The poem is tragic, sad and moody and does not offer a positive solution to an individual’s problems.
Answer:
In the light of this statement discuss the theme of the poem. The theme of the poem is tragic, sad and moody because it does not offer a positive solution to an individual’s desire to estimate the worth of one’s self. What she sees in the mirror is still a projection of her self—the ‘terrible fish’ that rises from under the objective surface. This inability to come to terms with a clear, objective point of view ‘unmisted’ by projections and preconceptions is really the central theme of the poem.

The Snake and the Mirror Extra Questions and Answers Long Answer Type

Question 1.
What kind of room was the doctor living in and why did he decide to leave that room?
Answer:
The doctor was living in was a small, uncomfortable room that was actually an outer room with one wall facing the open yard and two windows. The room was not electrified and he had to depend on a kerosene lamp for lighting. The roof was tiled and had long supporting gables which rested on a beam over the wall. The room did not have any ceiling and it was infested with rats that kept squeaking all the time.

Since his medical practice was yet not well-established, the doctor did not earn much and could not afford a better place. He was not happy with this poor accommodation but it was all he could afford on his meagre earnings. However, it was only after his encounter with the snake that he decided to leave it. The frightening experience left him shaken and he decided not to live in the room any longer.

Question 2.
What kind of a person was the doctor? What kind of a person did he want to be?
Answer:
The doctor had just started his practice. His earnings were, therefore, meagre. He lived in a small rented room, which was not electrified. He had only sixty rupees in his bag. Apart from a few shirts and dhotis, he had one solitary black coat. He lived alone in a house that was full of rats.

On the other hand, the doctor laid great emphasis on the fact that he was unmarried and a doctor. He was a great admirer of beauty and he believed in making himself handsome. He was pleased with his appearance. He decided to shave daily and grow a thin moustache to look more handsome. He also decided to smile more as it improved his appearance.

Question 3.
What kind of woman did the doctor want to marry? Whom did he get married to?
Answer:
The doctor took pride in his handsome looks and the fact that he was a doctor and a bachelor. He had just started his practice and had very little money, wanted to marry a woman doctor who had plenty of money and . a good medical practice. He wanted a fat wife so that whenever he would make a silly mistake and run away from his wife, she would not be able to run behind him or catch him. The woman he married was quite unlike the one he wanted to marry. She was a thin and slender person who could run like a sprinter.

Question 4.
Describe the doctor’s feelings when the snake coiled round his arm.
Answer:
The doctor was petrified when the snake landed on his shoulder. He didn’t jump, tremble or cry out. He sat there holding his breath, turned to stone. He thought his end was near, so he remembered the Almighty and prayed to God for his safety. However, he retained his presence of mind as well as his sense of humour. He forgot his danger and smiled feebly at himself. From admiring himself and vainly thinking of ways of making himself appear more handsome and arrogantly declaring he was a doctor and a bachelor, the doctor thought of himself as “a poor, foolish and stupid doctor.”

He did not have even the medicine to save himself in case he was bitten by the snake. As he sat there, with Death lurking four inches away, the narrator did not panic. With great patience he sat still, on the lookout for an opportunity to escape and as soon as the snake unwound itself from his arm, the doctor got up from the chair and went out quietly, and ran away to his friend’s house.

Question 5.
“I was but a poor, foolish and stupid doctor.” Justify.
Answer:
Initially, the doctor had a very high opinion of himself regarding both his appearance and profession. He laid great emphasis on the fact that he was unmarried and a doctor. As an admirer of beauty, he was conscious of his looks and wanted to look even more handsome. He admired himself in the mirror and combed his hair this way and that and decided to grow a moustache and smile more to look more attractive.

But an encounter with a snake – a cobra – cured him of his pride. When the snake wriggled over his shoulder and coiled itself around his arm, the doctor lost all arrogance and was reminded of the existence of God. Face to face with death, he realised what a weak and foolish man he had been. When he recalled that there were no medicines in his room to cure him of a snake-bite, he regarded himself to be a stupid and helpless person. Thus, the encounter with the snake transformed the doctor from a vain and foolish person into a humble and God-fearing man.

Question 6.
What are the similarities between the behaviour of the doctor and of the snake?
Answer:
Both the doctor and the snake display narcissistic tendencies. Both of them were enamoured by their reflections in the mirror and stared at them as if enamoured. When he looked in the mirror, the doctor was full of appreciation for his good looks. He was a great admirer of beauty and believed in making himself look handsome. He took a close look at his face and decided that he would shave daily and grow a thin moustache to look even more handsome. Then, he looked into the mirror and smiled. He decided to keep smiling as he considered his smile very attractive. As he gazed at himself in the mirror, he was oblivious of his surroundings. He heard the noise of the rats cease, he heard the snake drop to the ground with a dull thud, but he paid no heed and found himself face to face with death.

In the same manner, the snake gazed in the mirror, oblivious of his surroundings. This makes the doctor think , that perhaps it, too, was admiring its beauty or was trying to make some ‘important’ decisions just like him. Perhaps it was a male snake thinking about growing a moustache or a female one deciding to use eye shadow and mascara or wear a vermilion spot on its forehead. Just like the doctor’s obsession with his looks landed him in trouble, the snake too seemed to be “taken with its beauty.” It released its victim to have a better look at itself in the mirror.

Question 7.
This story about a frightening incident is narrated in a humorous way. What makes it humorous?
Answer:
The story presents a contrast between dreams and reality. This contrast has been depicted in a humorous manner. The doctor had meagre earnings as he had just started his practice. He lived in a small rented room, which was not electrified. He had only sixty rupees in his bag, a few shirts and dhotis, and one solitary black coat. His house was full of rats. However, his dreams and ambitions were in contrast to this. He was a great admirer of beauty and he believed in making himself handsome. He laid great emphasis on the fact that he was unmarried and a doctor. Pleased with his appearance, he decided to improve his appearance by shaving daily, growing a thin moustache and always keep smiling.The doctor had thought about the kind of person he would want to marry.

He wanted to marry a woman doctor who had plenty of money and a good medical practice because he did not have any of those. He wanted a fat wife so that whenever he made a silly mistake, he could escape his wife by running away from her. However, the woman he married was thin and could run like a sprinter. When the doctor looked into the mirror, he was full of appreciation for his good looks. He also arrogantly declared that he was a doctor and a bachelor.

However, later when the snake was coiled around his arm, he turned into a stone. He realized that if the snake struck him, then he did not even have any medicines in his room for the same. That was when he thought that he was a poor, foolish, and stupid doctor. This contrast between reality and dreams lends humour to the story.

Question 8.
“I looked into the mirror and smiled”, says the doctor. A little later he says, “I forgot my danger and smiled feebly at myself’. What is the doctor’s opinion about himself when he smiles first and then later? In what way do his thoughts change in between, and why?
Answer:
The doctor rated his looks quite high and smiled at his image when he looked at himself in the large mirror on his table. He was narcissistic and the first time he looked in the mirror and smiled, his opinion about himself was marked by self-adulation. He arrogantly declared he was a doctor and a bachelor. He was vain enough to believe that he was handsome and needed to stay well-groomed. He decided to shave daily, grow a moustache and smile more often.

However, these thoughts changed by the second time he smiles at himself in the mirror. This time the smile was feeble as he smiled at himself. On this occasion, his opinion about himself was marked by humility. By then he had realised that he had been vain, foolish and stupid. His encounter with the deadly snake had exposed his shortcomings to him. In spite of being a doctor he did not have any medicines in his room even for an emergency like a snake-bite. His good looks became immaterial when he came face to face with death and the only thoughts that came to his mind then were about God. The feeble smile indicated his acceptance of the folly and vanity that had so far governed his life.

They learned the same things, so they could help one another with the homework and talk about it. Margie thought about the old school system and how much fun the children must have had, learning and spending time together.

Question 3.
Write a short note on the school system in “The Fun They Had”.
Answer:
Margie and Tommy are young school going children in the year 2157. Schools and teachers in the twenty- second century are entirely different from the ones in present day. Margie and Tommy’s school is not in a separate special building but a room in their respective houses where the television or the mechanical teacher is placed. Each student has to sit and study alone with the help of mechanical teacher, a large and black and ugly machine, with a big screen on which all the lessons are shown and the questions are asked.

The ‘teacher’ assigns tests to the students and assesses their progress. The speed of the different subject sectors is fixed according to the age level of each student. There is a special slot in the tele-teacher where students have to insert their homework or tests. If the mechanical teacher develops any fault, there are engineers to repair it.

Sometimes the fault may be a major one and it takes long to repair it, as was the case when Tommy’s history teacher developed a snag and it took a month to repair it. Thus, the mechanical teachers and schoolrooms of Margie and Tommy are fully computerised and are completely different from the present day schools.

Question 4.
Do you agree that schools today are better than the schools in the story ‘The Fun They Had’. Give reasons for your choice.
Answer:
Yes: In the story The Fun They Had writer Isaac Asimov talks about the schools of the future. In this future, school is a room in the house where each child is taught by a mechanical teacher and there are telebooks on television screens.

After reading the story, I think that we pupils in the present should be satisfied. I agree an individual teacher for each child can work better and more intensively with the pupil and when the parents set the school time a child can have flexible school hours. If the school(room) is at home, the children do not have to walk or drive so far and this saves time and money.

But on the other hand, we lose an opportunity for social contacts. The most important advantage we have today is we have contact with other kids, in the breaks we can talk to each other and we have fun with them. Pupils solve problems together – very important for the later life and the development of a child. And a human teacher is definitely a better educator than a machine because he knows the problems of humans and children. A machine will never be able to feel like a human. Moreover, a human teacher can provide valuable guidance and values that a mechanical teacher cannot.

No: The Fun They Had by Isaac Asimov is a science-fiction story schooling in the twenty-second century. Margie, an eleven-year-old girl, and Tommy, who is thirteen, live in the year 2157, where school means learning from a machine teacher at home. Both kids have never seen a printed book, because they read telebooks.

The author shows us how school could be in two hundred years, when everything is managed by computers and other technology. In his story, in spite of the advances in technology, the two children are still like kids today. Isaac Assimov shows very clearly the typical behaviour of an eleven-year-old girl and a thirteen-year- old boy, so in his story their characters are not influenced by the technical advancement.

An advantage of a mechanical teacher is that the mechanical teacher can be geared to the mental level of the student. Thus, it becomes easier for the child to understand the lessons. Different styles of learning of students can be addressed using mechanical teacher and technology. Mechanical teachers can analyze the specific mistakes that students make and give instant feedback which would prove helpful for the students.

Question 5.
Do you think Asimov is warning us about the dangers of too much computerisation?
Answer:
In his short story “The Fun They Had” Isaac Asimov depicts the school system in 2157 which is based on technical advancement. Thirteen-year-old Tommy and eleven-year-old girl Margie both study with a computer teacher at home. While the individual teaching can train the personal talents and it is a perfect way to give every child knowledge and information baed on the child’s capacity, but there are some disadvantages, too.

Pupils do not learn like a computer. Learning has to be fun, otherwise the probability of forgetting is higher. Another disadvantage is that there are no social relationships like at school today. Learning with friends at school can be a motivation. Students improve their communication skills and their behaviour in a group. A mechanical teacher cannot give moral values to the children.

I think Asimov is trying to warn us that the school system which is being followed in 2157 is a good way of giving children knowledge and information for jobs, but it is not good at giving ability for interpersonal relationships. In my opinion the disadvantages are more serious than the advantages and I feel this is a warning given by Isaac Asimov that this kind of schooling may not, in fact, be an ideal option for students.
