Assertion : Impulsive force is large and acts for a short time. Reason : Finite change in momentum should be produced by the force.

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

Impulse = Force time duration = Change in momentum A large force acting for a short time to produce a finite change in momentum is called an impulsive force.
