Question

For a man standing inside a life, when will his apparent weight be equal to real weigh?

(a) When the life is moving upwards with a uniform acceleration

(b) When the lift is moving downwards with a uniform velocity

(c) At rest or moving with uniform velocity

(d) Falling freely

Answer 1

The correct answer is (c) At rest or moving with uniform velocity

To explain: When the life is in rest or moving with a uniform velocity, the acceleration = 0. Net force on the man is zero. Therefore apparent weight will be equal to real weight of the man.
