rotation

a thin circular ring of mass M and radius r is rotating about its axis with a constant angular velocity(omega).2 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 of? how do i start i need a hint....

Well the 'gently' means no extra angular momentum/energy is added to the ring.

So in order for the additional masses to pick up the rotational velocity of the ring it must loose some.

You seem to pick up very quickly on the hints.
I hope this means that you have achieved a good grasp of elementary mechanics.
Well done. Spotting things will come with practice.
