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

the normal force exerted on the inner and outer wheels are N_(2) and N_(1) respectively. Then N_(1)//N_(2) is When a car negotiates a curve
