Assertion : In rolling, all points of a ...

Assertion : In rolling, all points of a rigid body have the same linear velocity.
Reason : The rotational motion does not affect the linear velocity.

A

If both, Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

B

If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Here, both the assertion and reason are false because in case of a rolling body, all points on it have same angualr but different linear speed. Linear speed is different at different places. It is max. at highest point and minimum at lowest point.
