Physics - Circular Motion Question with Solution | TestHub

A hollow vertical cylinder of radius$\mathrm{R}$and height$\mathrm{h}$has a smooth internal surface. A small particle is placed in contact with the inner side of the upper rim at a point$\mathrm{P}$. It is given a horizontal speed${\mathrm{v}}_0$tangential to the rim. It leaves the lower rim at point$\mathrm{Q}$, vertically below$\mathrm{P}$. The number of revolutions made by the particle will be
