A body of mass `0.25` kg is projected with muzzle velocity `100ms^(-1)` from a tank of mass 100 kg. What is the recoil velocity of the tank

A

`5 ms^(-2)`

B

`25 ms^(-1)`

C

`0.5 ms^(-1)`

D

`0.25 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Using law of consevation of momentum, we get `100xxv=0.25xx100`
`implies v=0.25 ms^(-1)`
