A hollow sphere of mass `2 kg` is kept on a rough horizontal surface. A force of `10 N` is applied at the centre of the sphere as shown in the figure. Find the minimum value of `mu` so that the sphere starts pure rolling. (take `g=10 ms^(-2)`)

A hollow cylinder of mass m and radius r is kept on a smooth horizontal surface. Horizontal force F is applied at a height above the centre. Find the value of h/R so that ring performs pure rolling on the surface.

A hollow sphere of mass 'm' and radius 'R' are placed on horizontal surface and a horizontal force 'F' starts acting at a distance 'x' from its top most as shown in the figure.The value of 'x' such that hollow sphere starts pure rolling without use of friction is
