A gun of mass 10 kg fires 4 bullets per second. The mass of each bullet is 20 g and the vlocity of the bullet when it leaves the gun is `300 ms^(-1)` The force required to hold the gun while firing is :

Options

A. 6N
B. 8N
C. 24 N
D. 240 N

Answer

c

Explanation

Here the force applied = Rate of change of momentum`F=(Deltap)/(Deltat)n.mu upsilon=4xx20xx10^(-3)xx300=24N`
(c) is the choice,
