In an elevator the actual weight of a person is equal to the apparent weight when .

A

elevator is at rest

B

elevator is accelerating upwards

C

elevator is accelerating downwards

D

elevator is in uniform motion

Text Solution

Verified by Experts

The correct Answer is:
a,d
When elevator is at rest or in unifrom motion then
`a =0`
`:. W = n (g -a)` or `W (g + a)`
In both the cases `W = mg`
So real weight is equal to apparent weight when body is at rest or in unifrom motion.
