A spool of mass m has moment of inertia ...

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?

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: .

Choose the correct option: 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. Thread is pulled by a force F as shown in the figure. Then in case of pure rolling.

A spool is pulled at an angle theta with the horizontal on a rough horizontal surface as shown in the figure. If the spool remains at rest, the angle theta is equal to
