Question

Statement 1: When a man is standing on a stationary horizontal surface, the normal force exerted by the ground on him is equal and opposite to his weight.
Statement 2: According to Newton's $3^{rd}$ law , every action has an equal and opposite reaction.

• A. Statement 1 - is true, statement- 2 is true and statement-2 is NOT the correct explanation for statement-1
• B. Statement 1 - is true, statement- 2 is false
• C. Statement 1 - is true, statement- 2 is true and statement-2 is correct explanation for statement-1
• D. Statement 1 - is false, statement- 2 is true

Answer 1

Answer: (A)

The gravitational force and the normal force both act on the man and in Newton's third law the force pair of action-reaction is acting on different bodies. However, statement one is true, as the forces acting on the man balances itself. However, the reason is not the correct explanation.
Ans: (B)
