A stone is released from a rising balloon accelerating upward with acceleration a. The acceleration of the stone just after the release is

A

a upward

B

g downward

C

`(g-a)` downward

D

`(g+a)` downward

Text Solution

Verified by Experts

The correct Answer is:
B
Packet comes under gravity. Therefore only force is
mg.
`a=f/m=(mg)/m=g` (downwards)
