Physics - Rotation Question with Solution | TestHub

Two circular loops $\mathrm{P}$ and $\mathrm{Q}$ are made from a uniform wire. The radii of $P$ and $Q$ are $R_1$ and $R_2$ respectively. The moments of inertia about their own axis are ${\mathrm{I}}_{\mathrm{P}}$ and ${\mathrm{I}}_{\mathrm{Q}}$ respectively. If $\frac{{\mathrm{I}}_{\mathrm{P}}}{{\mathrm{I}}_{\mathrm{Q}}}=\frac{1}{8}$ then $\frac{{\mathrm{R}}_2}{{\mathrm{R}}_1}$ is
