As shown in the figure, a disc of mass `m` is rolling without slipping a angular velocity `omega`. When it crosses point `B` disc will be in `:`

A

translational motion only

B

pure rolling motion

C

rotational motion only

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
In BC section no force or torque is applied on disc so pure rolling motion will continue.
