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?
