3. The Attempt at a Solution
These are my two observations for this problem .
1) Center of mass of the ring moves in a circle of radius (R-r) about point O . O is the center of the smaller circle in figure 2 .
2) From the geometry , the angular speed of the CM of the ring is equal to the angular speed with which the finger is rotating i.e ω0 .
Now I am not sure how do I calculate the angular speed of the ring about its CM ( which coincides with its center ) .
I would appreciate if someone could help me with the problem .
Thanks
