A machine gun fires n bullets per second and the mass of each bullet is m. If the speed of the bullet is `upsilon` then, the force exerted on the machine gun is:

nmg

nm`upsilon`

nmug

nmu`upsilon`g

Text Solution

Verified by Experts

The correct Answer is:

`F=(dp)/(dt)=(p_(2)-p_(1))/(t)=(nm upsilon-0)/(1)=nm upsilon`
Hence correct choice is (b)
