NEET Physics Impulse & Momentum MCQ Question

Type: MCQ-diagram based-Medium-Class 11

Consider a diagram showing a bullet of mass m being fired from a gun of mass M. The bullet moves with velocity v after being fired. What is the recoil velocity of the gun?

Question diagram
A

-(m * v) / M

B

m * v * M

C

M / (m * v)

D

(m + M) * v

Correct Answer

Option A

Detailed Explanation

According to the conservation of momentum, the recoil momentum of the gun must equal the momentum of the bullet but in the opposite direction. Thus, the recoil velocity of the gun is -(m * v) / M.
