Assertion : KE is conserved at every instant of elastic collision. Reason : No deformation of matter occurs in elastic collision.

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

Kinetic energy is not conserved at every instant of elastic collision because there will be friction and deformation losses of energy.
