A lift is moving down with acceleration ...

A lift is moving down with acceleration a. A man in the lift drops a ball inside the lift. The acceleration of the ball as observed by the man in the lift and a man standing stationary on the ground are respectively

A

g,g

B

a,a

C

`(g-a),g`

D

`a,g`

Text Solution

Verified by Experts

The correct Answer is:
C
when dropped acceleration of the ball is g as will be observed by a man standing stationary on the ground .the man inside the lift is having its own downward acceleration a . Therefore relative acceleration of the ball as observed by the man in the lift `=(g-a)`
