364358 A uniform disc of mass \(m\) and radius \(R\) is connected with two light springs 1 and 2 . The springs are connected at the highest point \(M\) and the \(CM\) ' \(N\) ' of the disc. The other ends of the springs are rigidly attached with vertical walls. If we shift the CM in horizontal by a small distance, the disc oscillates simple harmonically. Assuming a perfect rolling of the disc on the horizontal surface, find the angular frequency of oscillation.
