Rotational MotionHard
Question
The figure shows a system consisting of (i) a ring of outer radius 3R rolling clockwise without slipping on a horizontal surface with angular speed ω and (ii) an inner disc of radius 2R rotating anti-clockwise with angular speed ω/2. The ring and disc are separated by frictionless ballbearings. The point P on the inner disc is at a distance R from the origin, where OP makes an angle of 300 with the horizontal. Then with respect to the horizontal surface,
Options
A.the point O has linear velocity 3Rω 
B.the point P has linear velocity 
C.the point P has linear velocity 
D.the point P has linear velocity
