Answer:

Hi Tushar,

Change in momentum of 1 bullet = mv

Force of recoil = Rate of change of momentum

n bullets are fired per second

Time for 1 bullet = 1 /n 

begin mathsize 12px style Force space equals space fraction numerator mv over denominator 1 divided by straight n end fraction equals mvn end style
