In the situation given, a force `F` is applied at the top of sphere. Study following statements.

Consider the system shown. A solide sphere (of mass m and radius R) is placed over a plak (of mass 2m and placed over a smooth horizontal surface.) A horizontal force F is applied at the top of the sphere, as shown. Consider that the friction between the sphere and plank is sufficient enough for no slipping of the sphere over then plank. Friction force acting between the sphere and the plank is

A constant horizontal force F is applied on the top of a solid sphere and a hallow sphere of same mass and radiuis both kept on a sufficiently rough surface. Let a_(S) and a_(H) be their linear acceleration respectively, then
