Q113 / 180 · AIIMS 2009 · Physics

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

Correct answer
A
If both assertion and reason are true and reason is the correct explanation of assertion
B
If both assertion and reason are true but reason is not the correct explanation of assertion
C
If assertion is true but reason is false
D
If both assertion and reason are false.

Solution

Impulse $=$ Force $\times$ 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.

Hence, the correct answer is option: 'A'.
