Question

A massless string is wrapped around a solid cylinder having mass m and radius r. The cylinder is kept on a rough
horizontal surface (coefficient of friction is u ). A constant force F is applied as shown in the figure. In case of pure rolling,
the friction force acting on the bottom most point of the cylinder is F/k. Find k.
