Physics - Rotation Question with Solution | TestHub

A linear rod of mass m , length $\ell$ is placed as shown in figure such that its one end rests on a rough table of friction coefficient $\mu$. When string BS is cut, rod AB starts falling from rest. After rotating an angle $\theta ={\tan }^{-1}\left(\frac{\mu }{2\mathrm{x}}\right)$, rod starts slipping on the table, find x ?
