A gun of mass 10 kg fires 4 bullets per second. The mass of each bullet is 20 g and the velocity of the bullet, when it leaves the gun, is 300 ms -1 . The force required to hold the gun while firing is
Text Solution
Verified by ExpertsThe correct answer is:
C
24 N
Rate of change of momentum of the bullet in forward direction = Force required to hold the gun.
F = nmv = 4 x 20 x 10 -3 x 300 = 24 N
