If the moment of inertia of a solid sphere of mass M and radius R about its diameter is I, then that of another sphere of mass 2M and radius 2R about its diameter is
If the moment of inertia of a solid sphere of mass M and radius R about its diameter is I, then that of another sphere of mass 2M and radius 2R about its diameter is
Show Hint
\(I \propto MR^2\). If M doubles and R doubles, \(I\) becomes \(2 \times 4 = 8\) times.
