Q.18 A solid cylinder C of mass 10 kg rolls without slipping in an inclined plane which offers frietion. The angle of the inclined plane with the horizontal is 30 as shown in the figure below. A massless inextensible string is wrapped around the cylinder and it passes over a frictionless pulley, P. The other end of the string holds a block B of mass 2 kg as shown in the igure. T'ake g =l0 ms (a) Draw the free body diagram of the eyiinder and the block. If the block B moves down by U.0l m, how much distance does C move along the inchne (b) If the block B moves with an acceleration of 0.05 g upward, find the magnitude of (12) the frictional force.
