Physics - Rotation Question with Solution | TestHub

A uniform wooden stick of mass 1.6 kg and length$\mathcal{l}$rests in an inclined manner on a smooth, vertical wall of height h$\left(<\mathcal{l}\right)$such that a small portion of the stick extends beyond the wall. The reaction force of the wall on the stick is perpendicular to the stick. The stick makes an angle of${30}^o$with the wall and the bottom of the stick is on a rough floor. The reaction of the wall on the stick is equal in magnitude to the reaction of the floor on the stick. The ratio h/$\mathcal{l}$and the frictional force f at the bottom of the stick are:$\left(g=10 m{s}^{-2}\right)$
