Problem

A thin circular ring of mass

M

and radius

r

is rotating about its axis with a constant angular velocity

\omega

. Two objects, each of mass

m

, are attached gently to the opposite ends of a diameter of the ring. The wheel now rotates with an angular velocity a.

\frac{\omega M}{(M+m)}

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

\frac{\omega M}{(M+2m)}

\frac{\omega (M+2m)}{M}
