A body of mass 1.0 kg is falling with an acceleration of 10 ms⁻².

A body of mass 1.0 kg is falling with an acceleration of 10 ms⁻². Its apparent weight will be (g=10 ms⁻²)

Options

(a) 1.0 kg wt
(b) 2.0 kg wt
(c) zero
(d) 0.5 kg wt

Correct Answer:

zero

Explanation:

R = m (g – a) = m (10 – 10) = zero
This answer is an extension of the lift problem. Actually mg is the force acting on the mass m. As potential energy decreases, its kinetic energy increases as experienced. The question is not correct.
