A body of mass 0.25 kg is projected with...

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

A

`5 ms^(-1)`

B

`25 ms^(-1)`

C

`0.5 ms^(-10)`

D

`0.25 ms^(-1)`

Text Solution

Verified by Experts

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