A thin circular ring of mass M and radius R is rotating about its axis with a constant angular velocity omega. Four objects each of mass m, are kept gently to the opposite ends of two perpendicular diameters of the ring. What will be the angular velocity of the ring?

`(m omega)/(m+M)`

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

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

`((m-2M)omega)/(m+2M)`
