Physics - Rotation Question with Solution | TestHub

Two spheres having masses ${\mathrm{m}}_1$ and ${\mathrm{m}}_2$ are kept on a on a inclined plane as shown. Both of them are in equilibrium. What is a necessary condition for this? ( ${\mu }_1$ is coefficient of friction between ${\mathrm{m}}_1$ and inclined plane and ${\mu }_2$ is coefficient of friction between ${\mathrm{m}}_2$ and inclined plane).
