A spool of thread of mass m is placed on an inclined smooth plane set at an angle`theta` to the horizontal. The free end of the thread is attached to the wall as shown in figure-5.74. Calculate the acceleration of the centre of mass of the spool , if its moment of inertia about its axis is Iand the radius of the wound thread layer is r.
`[("g sin" theta)/(1 + (I)/(mr^(2)))]`
