A gun of mass 10kg fires 4 bullets per second. The mass of each bullet is 20 g and the velocity of the bullet when it leaves the gun is `300ms^(-1)`. The force required to hold the gun while firing is

A

24N

B

28N

C

32N

D

10N

Text Solution

Verified by Experts

The correct Answer is:

A

Force= Rate of change of momentum
`=(mass)/(time) times velocity = (20/100 times 4) times 300=24N`
