A thin circular ring of mass $\displaystyle M$ and radius $\displaystyle R$ is rotating in a horizontal plane about an axis vertical to its plane with a constant angular velocity $\displaystyle \omega$. If two objects each of mass $\displaystyle m$ be attached gently to the opposite ends of a diameter of the ring, the ring will then rotate with an angular velocity :
Official answer
(3)
$\displaystyle \frac{\omega M}{M+2 m}$
