A machine gun has a mass 5 kg. It fires 50 gram bullets at the rate of 30 bullets per minute at a speed of `400" m s"^(-1)`. What force is required to keep the gun in positon ?

A

10 N

B

5 N

C

15 N

D

30 N

Text Solution

Verified by Experts

The correct Answer is:
A
Force required `=("change in momentum")/("time taken")`
`=((50xx10(-3)xx30)xx400-(5xx0))/(60)=10N`
