Question

If a bullet was fired from a gun, then choose the best option.

• A. Since the mass of bullet is very less than the mass of the gun, the momentum of bullet is not equal to the momentum of gun
• B. The momentum of gun is twice the momentum of bullet
• C. The momentum of gun is equal to momentum of bullet
• D. During firing, the law of conservation of momentum does not hold true

Answer 1

The correct option is C

The momentum of gun is equal to momentum of bullet

Bullet and Gun – When a bullet is fired from a gun, gun recoils in the opposite direction of the bullet. The momentum of the bullet is equal to the momentum of the gun. In the case of the firing of the bullet, the law of conservation of momentum is applied. As the explosive force is an internal force for the gun-bullet system.
