Newton’s Third Law
Laws of Motion Class-9 Exe-3D MCQs Concise Physics ICSE Selina Solutions Ch-3
Page 80 (Choose the correct answer from the options given below).
Que-1: Newton’s third law :
(a) defines the force qualitatively
(b) defines the force quantitatively
(c) explains the way a force acts on a body
(d) gives the direction of force.
Ans: (c) explains the way a force acts on a body
Hint- Newton’s third law explains the way a force acts on a body and states that, to every action there is always an equal and opposite reaction.
Que-2: Which law of motion explains how a force acts on a body or an object /
(a) Newton’s third law
(b) Newton’s second law
(c) Newton’s first law
(d) All of the above
Ans: (a) Newton’s third law
Que-3: To every action there is always :
(a) an equal reaction
(b) an equal and opposite reaction
(c) an equal reaction in the same direction
(d) none of these
Ans: (b) an equal and opposite reaction
Que-4: Action and reaction act on the :
(a) same body in opposite direction
(b) different bodies in opposite directions
(c) different bodies, but in same direction
(d) same body in same direction
Ans: (b) different bodies in opposite directions
Que-5: The motion of a boat moving away from the shore is an example of :
(a) Newton’s first law
(b) Newton’s second law
(c) Newton’s third law
(d) not related with Newton’s law
Ans: (c) Newton’s third law
Hint- To move a boat ahead in water, the boatman pushes (action) the water backwards with his oar and at the same time, the water exerts an equal and opposite force (reaction) in the forward direction on the boat due to which the boat moves ahead. Hence, it is an example of Newton’s third law
Que-6: In an interaction of two bodies A and B, which of the following statements is correct ?
(a) F¯AB = F¯BA
(b) F¯BA ≥ F¯AB
(c) F¯AB = -F¯BA
(d) F¯AB > F¯BA
Ans: (c) F¯AB = -F¯BA
Que-7: A footballer hits a football with a force of 10 N. What force does the footballer experience ?
(a) 5 N
(b) 10 N
(c) 20 N
(d) 15 N
Ans: (b) 10 N
Hint- According to Newton’s third law to every action there is always an equal and opposite reaction. Hence, the footballer will also experience a reaction force of 10 N.
Que-8: Out of the following statements, which one is correct ?
(a) the sum of action and reaction on a body is zero.
(b) action and reaction act on different bodies in opposite direction.
(c) action and reaction are always in opposite direction on the same body.
(d) action and reaction act on different bodies in the same direction.
Ans: (b) action and reaction act on different bodies in opposite direction.
Hint- The action and reaction never act on the same body, but they always act simultaneously on two different bodies i.e., the forces on interaction are always present in a pair.

Que-9: Which of the following are examples of Newton’s third law of motion?
(i) While catching a ball, the cricketer withdraws his hands along with the ball.
(ii) Athletes often land on sand after taking a high jump.
(iii) Motion of a man on ground
(a) (iii)
(b) (ii)
(c) (i)
(d) all of the above.
Ans: (a) (iii)
Hint- When a man applies a force F (action) backward by his foot on the ground against the force of friction, the ground exerts an equal and opposite force R (reaction) forward on his foot. The horizontal component of the force of reaction enables the man to move forward.
