Physics 2014 Solved Question Paper Previous Year ICSE Class 10



SECTION-I (40 Marks)

Attempt all questions from this Section

Question 1:

(a) A force is applied on (i) a non-rigid body and (ii) a rigid body. How does the effect of the force differ in the above two cases ? [2]
(b) A metallic ball is hanging by a string from a fixed support. Draw a neat labelled diagram showing the forces acting on the bail and the string. [2]
(c) (i) What is the weight of a body placed at the centre of the earth ?
(ii) What is the principle of an ideal machine ? [2]
(d) Is it possible to have an accelerated motion with a constant speed ? Explain. [2]
(e) (i) When does a force do work ?
(ii) What is the work done by the moon when it revolves around the earth ? [2]


(a) A force when applied on a rigid object does not change the inter-spacing between its constituent particles and therefore it does not change the dimensions of the object, but causes motion in it. On the other hand, a force when applied on a non-rigid object, change the inter-spacing between its constituent particles and therefore cause a change in its dimensions.


(c) (i) The weight of a body placed at the centre of the earth is zero.
(ii) An ideal machine is that in which there is no dissipation of energy in any manner. The work output is equal to the work input i.e., 100% efficiency.



(d) Yes. The velocity of particle in circular motion is variable or the circular motion is accelerated even though the speed of particle is uniform.

(e) (i) Work is said to be done only when the force applied on a body makes the body moves (i.e., there is displacement of the body).
(ii) The work done by the moon when it revolves around the earth is zero.

Question 2:

(a) Calculate the change in the Kinetic energy of a moving body if its velocity is reduced to 113rd of the initial velocity. [2]
(b) State the energy changes in the following devices while in use:
(i) A loud speaker.
(ii) A glowing electric bulb. [2]
(c) (i) What is nuclear energy ?
(ii) Name the process used for producing electricity using nuclear energy. [2]
(d) State one important advantage and disadvantage each, of using nuclear energy for producing electricity. [2]
(e) (i) The conversion of part of the energy into an undesirable form is called ………. .
(ii) For a given height h, ………… the length l of the inclined plane, lesser will be the effort required. [2]


(b) (i) Electrical energy converted to sound energy.
(ii) Electrical energy converted to light and heat energy.

 (c) (i) In nuclear fission and fusion there is a loss in mass due to loss in mass energy is released. The energy so released is called the nuclear energy.

(ii) Nuclear fission.

(d) Advantage: A very small amount of nuclear fuel can produce a tremendous amount of electricity energy.
Disadvantage: Very harmful nuclear radiations are produced in the process which are highly energetic and penetrating.

(e) (i) Dissipation of energy. (ii) More.

Question 3:

(a) Draw the diagram given below and clearly show the path taken by the emergent ray. [2]
icse-previous-papers-solutions-class-10-physics-2014-3(b) (i) What is consumed using different electrical appliances, for which electricity bills are paid ?
(ii) Name a common device that uses electromagnets. [2]
(c) (i) A ray of light passes from water to air. How does the speed of light change ?
(ii) Which colour of light travels fastest in any medium except air ? [2]
(d) Name the factors affecting the critical angle for the pair of media. [2]
(e) (i) Name a prism required for obtaining a spectrum of Ultraviolet light.
(ii) Name the radiations which can be detected by a thermopile. [2]


(b) (i) Electrical energy.
(ii) Electrical bell.
(c) (i) Light travels denser to rarer, speed of light increases.
(ii) Red colour of light travels fastest in any medium except air.
(d) Factors affecting the critical angle for the pair of media are :
(i) Effect of colour and
(ii) Effect of temperature.
(e) (i) Quartz prism.
(ii) Infrared radiations can be detected by thermopile.

 Question 4:


(a) Why is the colour red used as a sign of danger ? [2]
(b) (i) What are mechanical waves ?
(ii) Name one property of waves that do not change when the wave passes from one medium to another. [2]
(c) Find the equivalent resistance between points A and B. [2]
icse-previous-papers-solutions-class-10-physics-2014-5(d) 50g of metal piece at 27 °C requires 2400 J of heat energy so as to attain a temperature of 327 °C. Calculate the specific heat capacity of the metal. [2]
 An electron emitter must have ……….. work function and ………… melting point. [2]


(a) Since the wavelength of red colour is maximum in the visible light, the light of red colour is scattered least by the air molecules of the atmosphere and therefore it can reach to a longer distance.
(b) (i) The sound waves require a medium for their propagation. These waves travel in the medium though the vibrations of the medium particles about their mean positions, so they are also called elastic or mechanical waves.
(ii) Frequency.
(e) An electron emitter must have low work function and high melting point.

(ii) Two forces each of 5N act vertically upwards and downwards respectively on the two ends of a uniform metre rule which is placed at its mid-point as shown in the diagram. Determine the magnitude of the resultant moment of these forces about the midpoint. [4]
icse-previous-papers-solutions-class-10-physics-2014-8(b) (i) A body is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy as its velocity becomes zero ?
(ii) Draw a diagram to show how a single pulley can be used so as to have its ideal M.A = 2. [3]
(c) Derive a relationship between mechanical advantages, velocity ratio and efficiency of a machine. [3]
