Assertion : A solid sphere cannot roll w...

Assertion : A solid sphere cannot roll without slipping on smooth horizontal surface
Reason : If the sphere is left free on smooth inclined surface. It cannot roll without slipping.

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:
D
Sphere can roll without slipping on surface, if `v = r omega` on an inclined plane, it is friction which creates rotation on sphere. So smooth surface can not create rotation.
