NEET Physics Impulse & Momentum MCQ Question
Consider two objects, a bullet and a gun, placed at rest on a frictionless surface. A diagram shows the bullet being fired from the gun in one direction. What can be said about the momenta of the bullet and the gun after firing?
The momentum of the bullet is equal in magnitude and opposite in direction to the momentum of the gun.
The momentum of the bullet and the gun are equal in both magnitude and direction.
The momentum of the bullet is greater in magnitude than the momentum of the gun.
The momentum of the bullet is less in magnitude than the momentum of the gun.
Correct Answer
Detailed Explanation
According to the law of conservation of momentum, in an isolated system, the total momentum before and after an event is the same. Thus, the momentum of the bullet is equal in magnitude and opposite in direction to the momentum of the gun.
