A sphere is performing pure rolling on a rough horizontal surface with constant angular velocity. Frictional force acting on the sphere is zero.
Velocity of contact point is zero.

A

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

B

If both assertion and reason are reason are true 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:
B
(b) If angular velocity is constant then frictional force acting on sphere is zero. In case of pure rolling velocity of contact point in zero.
