Question

The apparent weight of a man in a lift is less than the real weight when:

• A. the lift is going up with an acceleration
• B. the lift is going down with uniform speed
• C. the lift is going up with uniform speed
• D. the lift is going down with an acceleration

Hint:

Apparent weight depends on the acceleration of the lift. If the lift accelerates downward, the apparent weight decreases.

Answer 1

The Correct Option is D

When the lift is accelerating downwards, the apparent weight of a person inside it is less than their actual weight. This happens because the downward acceleration of the lift reduces the normal force exerted on the person, resulting in a lower apparent weight. Thus, the correct answer is (d) the lift is going down with an acceleration.
