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.

(iii)

Reason — 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.

Obviously, it will be difficult to move on a slippery road where friction is less.
