answered-by-expert Expert Answer

Torque = MI x Angular Acceleration.

Angular Acceleration = Torque/MI

Hence lower the MI higher will be angular acceleration and higher will be the gain in speed.

The MI of solid cylinder MR2/2 is small compared to that of hollow spherer 2MR2/3.

Solid cylinder to acquire greater speed.

A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
