A wheel ( to be considered as a ring ) of mass m and radius R rolls without sliding on a horizontal surface with constant velocity v. It encounters a step of height R/2 at which it ascends without sliding

A

the angular velocity of the ring just after it comes in contact with step is 3v/4R

B

the normal reaction due to the step on the wheel just after the impact is `(mg)/(2)-(9mv^(2))/(16R)`

C

the normal reaction due to the step on the wheel increases as the wheel ascends.

D

the friction will be absent during the ascent.
