Question
A ring of mass M and radius R sliding with a velocity v0 suddenly enters rough surface where the coefficient of friction is 
, as shown in figure. Choose the correct statement(s)
- As the ring enters on the rough surface, the limiting friction force acts on it
- The direction of friction is opposite to the direction of motion
- The friction force accelerates the ring in the clockwise sense about its centre of mass
- As the ring enters on the rough surface it starts rolling
The correct answer is: As the ring enters on the rough surface, the limiting friction force acts on it
