Physics - Rotation Question with Solution | TestHub

Two discs having moment of inertia ${\mathrm{l}}_1$ and ${\mathrm{I}}_2$ are made from same material have same mass. Their thickness and radii are ${\mathrm{t}}_1,{\mathrm{t}}_2$ and ${\mathrm{R}}_1,{\mathrm{R}}_2$ respectively. The relation between moment of inertia of each disc about an axis passing through its centre and perpendicular to its plane and its thickness is
