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 on the ground are, respectively:

a,g

`(g-a),g`

a,a

g,g

Text Solution

Verified by Experts

The correct Answer is:

`vec(a)_(b,l)=vec(a)_(b)-vec(a)_(l)=(g-a)darr implies vec(a)_(b) = g darr`.
