MCQ
A thin circular ring of mass $M$ and radius $R$ is rotating with a constant angular velocity $2 \; rads ^{-1}$ in a horizontal plane about an axis vertical to its plane and passing through the center of the ring. If two objects each of mass $m$ be attached gently to the opposite ends of a diameter of ring, the ring will then rotate with an angular velocity (in $rads ^{-1}$ )
- A$\frac{M}{(M+m)}$
- B$\frac{( M +2 m )}{2 M }$
- ✓$\frac{2 M }{( M +2 m )}$
- D$\frac{2( M +2 m )}{ M }$
