  Two blocks P and Q of masses 2 kg and 1.5 kg, respectively, are connected by a massless string passing over a frictionless pulley fixed at the upper edge of a cube S, as shown in the figure. Block P lies on the frictionless horizontal top surface of the cube, while block Q remains in contact with the vertical side surface, where the coefficient of friction is μ. The cube accelerates horizontally to the right with acceleration g/2. During this motion both P and Q remain stationary relative to the cube. Taking g = 10 m·s⁻², find μ.

  In the given arrangement of a doubly inclined plane two blocks of masses M and m are placed. The blocks are connected by a light string passing over an ideal pulley as shown. The coefficient of friction between the surface of the plane and the blocks is 0.25. The value of m, for which M = 10 kg will move down with an acceleration of 2 m s⁻², is: [Take g = 10 m s⁻² and tan37° = 3/4
