NEET Physics Conservation of Momentum MCQ Question
Type: MCQ-conceptual-Easy-Class 11
A gun fires a bullet of mass 50 g with a velocity of 30 m sec⁻¹. Because of this the gun is pushed back with a velocity of 1 m sec⁻¹. The mass of the gun is
A
15 kg
B
30 kg
C
5 kg
D
20 kg
Correct Answer
Option A
Detailed Explanation
Using the conservation of momentum, m₁v₁ = m₂v₂, where m₁ and v₁ are the mass and velocity of the bullet, and m₂ and v₂ are the mass and velocity of the gun. Solving gives m₂ = 15 kg.
