Question

Assertion : Impulsive force is large and acts for a short time.

Reason : Finite change in momentum should be produced by the force.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (a) Both A and R are true and R is the correct explanation of A

Explanation :

Impulse = Force x 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.
