NEET2017PhysicsCenter of Mass, Momentum and CollisionActual

Assertion : A particle strikes head-on with another stationary particle such that the first particle comes to rest after collision. The collision should necessarily be elastic. Reason : In elastic collision, there is a loss of momentum of the system of the particles.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Momentum of a system remains conserved in any kind of collision.
