A thin circular ring of mass M and radius R is rotating about its axis with a constant angular velocity ω. Two objects, each of mass m are attached gently to the opposite ends of a diameter of the ring. The ring now rotates with an angular velocity

A. ωM/m+M
B. ω(M−2m)/M+2m
C. ωM/M+2m
D. ω (M+2m/M)
