Question

A boy of mass 40 kg is standing in a lift,
which is moving downwards with an acceleration
9.8 m/s2. The apparent weight of the boy is
(Take g = 9.8 m/s)
(1) 40 x 9.8 N (2) Zero
(3) 40/9.8 N
(4) 40 N​

Answer 1

Answer:

l is the answer is correct

Answer 2

where is a force which is applied by the Earth or the gravitational force on any body.

since we know that the acceleration of gravitation is 9.8 metre per second square and also the lift has an acceleration of 9.8 metre per second square both the acceleration are equal so the boy's Apparent weight would be zero.
