Inner and outer radii of a spool are r and R respectively. A thread is wound over its inner surface and placed over a rough horizontal surface. Then: .

A spool of mass m has moment of inertia I= 2mR^(2) about its axis of symmetry. The inner and outer radius of spool R and 2R respectively. Thread is wounded on the inner cylinder and its one end is pulled a force F acting at angle theta with horizontal. The surface is sufficiently rough and th.e spool never slides on the surface. Regarding to the direction of rotation of spool which of the following statement is true?

A spool of mass m has moment of inertia I= 2mR^(2) about its axis of symmetry. The inner and outer radius of spool R and 2R respectively. Thread is wounded on the inner cylinder and its one end is pulled a force F acting at angle theta with horizontal. The surface is sufficiently rough and th.e spool never slides on the surface. Maximum frictional force acting on the spool is:

Thread is wounded on the inner cylinder and its one end is pulled a force F acting at angle theta with horizontal. The surface is sufficiently rough and th.e spool never slides on the surface. For theta=60^(@) the acceleration of spool is
