A gun of mass 10 kg 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

6 N

B

8 N

C

24 N

D

240 N

Text Solution

Verified by Experts

The correct Answer is:
C
Rate of change of momentum of the bullet in forward direction = Force required to hold the gun.
`rArr nmv = F rArr F = 4 xx 20 xx 10^(-3) xx 300`
= 24N.
