Assertion : A glass ball dropped on concrete floor can easily get broken compared if it is dropped on wooden floor. Reason : On concrete floor glass ball will take less time to come to rest.

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

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

Force exerted by concrete floor is more because change in momentum is fast.
