Question

2. A thin circular ring of mass M and radius R is rotating in a horizontal plane about an axis
vertical to its plane with a constant angular velocity If two objects each of mass m be
attached gently to the opposite ends of a diameter of the ring, the ring will then rotate with
an angular velocity:
1) WM/(M + 2m)
2) (W/M + 2m))/M
3) WM/(M + m)
4) (W/M - 2m))/(M + 2m)​

Answer 1
