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 $\omega$. 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 $\frac{M\omega}{M+2m}$ $\frac{(M+2m)\omega}{M}$ $\frac{M\omega}{M+m}$ $\frac{(M-2m)\omega}{M+2m}$
