A
Answer to Problem 1OQ
Solution: Both heavier player and lighter player exert force, each is equal in magnitude and opposite in direction. Hence option (A),
Explanation of Solution
Newton’s third law of motion states that for every action, there is an equal and opposite reaction. Force exerted by a heavier player on the lighter player is an action-reaction pair to force exerted by a lighter player on the heavier player. So, both forces have the same magnitude but opposite in direction. Hence, option (A) is the correct option.
Conclusion:
Two objects exert equal and opposite force on each other, it does not matter which is lighter and which is heavier.
