Assertion : Two identical spherical ball...

Assertion : Two identical spherical balls are released from two inclined plane. First is sufficiently rough and second is smooth. Both the balls will have same kinetic energy on reaching the bottom

Reason : Linear velocity of second ball will be more.

A

If both Assertion and Reason are correct 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 fasle

D

If Assertion is false but Reason is true

Text Solution

Verified by Experts

The correct Answer is:
B
In first case, work done by friction will be zero. That's why mechanical energy will remain conserved. Further, in second case, linear velocity will be more because this ball has only translation kinetic energy.
