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 ring now rotates with an angular velocity `omega' =`

A

`frac(2 omega M)((M-2m)`

B

`frac((M-2m)(M)`

C

`frac(omega M)((M+2m)`
