When we release a stone from a balloon which ascends with a velocity `v` and acceleration `a`, the velocity and acceleration of the stone just after release are :

Options

A. `v uarr, (g+a)darr`
B. `v uarr, (g-a) darr`
C. `v uarr, g darr`
D. `v uarr, (a-g) uarr`

Answer

C

Explanation

When we release the stone, velocity of stone will be the same as the balloon at time of releasing. Since after releasing. Stone is not attached with balloon the only acceleration is due to gravity, that is 'g' downward.
`v uarr, g darr`.
