a 25 kg uniform solid sphere with a 20 cm radius is suspended by a vertical wire such that the point of suspension is vertically above the centre of the sphere. a torque of 0.10 N-m is required to rotate the sphere through an angle of 1.0 rad and then the orientation is maintained.if the sphere is released then its time period of the oscilaation will be a- sec c- sec b- sec d- sec the correct answer is d . plz tell me how should we solve this problem.
