Angular velocity

The figure attached shows two masses held together by a thread on a rod that is rotating about its center with angular velocity w. If the thread breaks, the masses will slide out to the ends of the rod. How will that affect the rod’s angular velocity. Will it increase, decrease, or remain unchanged? Explain.

My attempt:

w= V/R

Neither of the two variables change, wouldn’t it remain unchanged?

Thanks!
