Assertion: In a perfectly inelastic collision in the absence of external forces , the kinetic energy is never conserved.
Reason: The objects deformed and stick together in this type of collision.

A

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

B

If both assertion and reason are true not 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.

Text Solution

Verified by Experts

The correct Answer is:
A
In a perfectly inelastic collision the objects in the absence of external forces, get deformed and stick together hence the kinetic energy is never conserved
