Physics - Rotation Question with Solution | TestHub

Two bodies rotate with kinetic energies ' $E_1$ ' and ' $E_2$ '. Moment of inertia about their axis of rotation are ' $I_1$ ' and ' $I_2$ '. If $I_1=\frac{I_2}{3}$ and ${\mathrm{E}}_1=27{\mathrm{E}}_2$, then the ratio of angular momenta ' ${\mathrm{L}}_1$ ' to ' ${\mathrm{L}}_2$ ' is
