Moment of intertia

Question

A solid sphere of radius R is rotating about an axis passing through its centre with a time period 0.5 seconds. During the rotation, if the sphere suddenly changes into a solid cylinder of height R3such that axis of cylinder coincides with axis of rotation, the time period of rotation of cylinder is

Moderate
Solution

Iω=I×2πT=constantTΙI1I2=2/5R2R22/2 and 43πR3=πR22×R3R2=2RT1T2=15T2=2.5sec
