Physics - Rotation Question with Solution | TestHub

Solid and hollow balls can be distinguished by any of the three methods.
Here we have,${\mathrm{I}}_{\mathrm{h}}>{\mathrm{I}}_{\mathrm{s}}$.
When torques are equal, angular acceleration$\mathrm{\alpha }$of hollow must be smaller than$\mathrm{\alpha }$of solid. Similarly, on rolling, solid ball will reach the bottom before the hollow ball
