Bullets of mass $50g$ are fired from a gun of mass $10 \,kg$ with velocity of $300\, m/s$. If $5\, bullets$ are fired per second then what force a person will have to apply on the gun so that it does not recoil ............ $N$

A

$75$

B

$150$

C

$225$

D

$300 $

Solution

$F=\operatorname{mn} \mathrm{V}$

$=\frac{50}{1000} \times 5 \times 300=75 \mathrm{N}$
