The device shown in Fig. rotates on the vertical axle as shown. The frame has negligible mass as compared to the four masses each of mass `m`. Initial angular velocity of the system is `omega_(0)`. Due to an internal mechanism the spokes in the frame lengthen so that the radii of the masses become `2a`. Initially, it was a. What will be the new angular velocity of the system?
