1. A wedge of mass M can slide on two parallel rails A and B inclined at anangle to the horizontal. In the middle of the rails and parallel to themruns a frictionless rod C that wears a light ring D. The rod does nottouch the wedge. A light inextensible cord attached with the ring runsthrough a hole in the wedge without touching it, then runs round anideal pulley on the top of the wedge and finally attached to a block ofmass m that can slide along the vertical face of the wedge withoutfriction as shown in the figure. Coefficient of friction between the wedgeand the rails is u. Initially the system is held motionless and thenreleased. Find the acceleration of the block. Acceleration due to gravityABis g.
