1.	A thin circular ring of mass m and radius R is rotating about its axis with a constant angular velocityω. 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 ω‘, which is equal to?
A.	mω/(m+M)
B.	mω/(m+2M)
C.	((m+2m)ω)/m
D.	((m-2M)ω)/((m+2M))
Answer» C.
