A ring of mass `M` and radius `R` sliding with a velocity `v_(0)` suddenly enters inthrough surface where the coefficient of friction is `mu`, as shown in figure.
.
Choose the correct statement (s).

A

As the ring enters on the rough surface, the limiting friction force acts on it.

B

The direction of friction is opposite to the direction of motion

C

The friction force accelerated the ring in the clockwise sense about its centre of mass

D

As the ring enter on the rough surface it starts rolling.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C

(A) Since at the time of entering the rough surface it will have forward sliding so limiting friction will act.
(B) It is having forward sliding so friction is opposite to direction of motion
( C) Due to friction force it will have a torque is clockwise direction
(D) it will have rolling after some time.
