A spool with a thread wound on it is placed on a smooth inclined plane set at an angle of 30 to the horizontal. The free end of the thread is attached to the wall as shown. The mass of the spool is m r m  200g, its moment of inertia relative to its own axis is I 0.45gm2, the radius of the wound thread layer is r 3 cm. The acceleration of the spool axis is:

A time varying force F = 2t is applied on a spool as shown in figure. The angular momentum of the spool at time t about bottommost point is:

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:

Figure shows a spool with thread wound on it placed on a smooth plane inclined at angle from horizontal. The spool has mass m, edge radius R , and is wound up to a radius r. its moment of inertia about its own axis is I . The free end of the thread is attached as shown in the figure. So that the thread is parallel to the inclined plane. T is the tension in the thread. Which of the following is correct?

The figure (A) and (B) shows two different arrangements of a spool being pulled with a constant force F in each case. Identify the direction of motion of centre of mass, and the direction of friction force in each case (i) The centre of mass moves along _______ x-axis in figure (A). (negative/positive) (ii) The frictional force acts along ___________ x-axis in figure (A). (negative/positive) (iii) The centre of mass moves along ____________ x-axis in figure (B). (negative/positive) (iv) The frictional force acts along _____________ x-axis in figure (B). (negative/positive)
