Question

Assertion: Collision between two billiard's ball are inelastic 

Reason: Momentum remains conserve during the collision 

(1) If both assertion and reason are true and reason is the correct explanation of assertion. 

(2) If both assertion and reason are true but reason is not the correct explanation of assertion. 

(3) If assertion is true but reason is false. 

(4) If both assertion and reason are false.

Answer 1

Correct option (2) If both assertion and reason are true but reason is not the correct explanation of assertion.

Explanation:

billiard's ball are not perfect elastic body. Some part of initial kinetic energy is lost in form of deformation energy and momentum remain conserved during every collision.
