Pure Rolling || Friction

Rolling friction is:

A massless string is wrapped around a hollow cylinder having mass m and radius r . The cylinder is kept on a rough horizontal surface (coefficient of friction is mu ). 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

A disc is rolling on a rough horizontal surface. The instantaneous speed of the point of contact during perfect rolling is zero with respect to ground. The force of friction can help in achieving pure rolling condition.
