Consider an equilateral triangular plate of mass 4m of side a . Consider two cases: (i) a point mass 4m is placed at the vertex P of the plate (ii) a point mass m is placed at the vertex R of the plate. In both cases the x coordinate of centre of mass remains the same. Then x coordinate of centre of mass of the plate is:

A block of mass M is tied to one end of a massless rope. The other end of the rope is in the hands of a man of mass 2M as shown in figure. The block and the man are resting on a rough wedge of mass M. The whole system is resting on a smooth horizontal surface. The man starts walking towards right while holding the rope in his hands. Pulley is massless and frictionless. Find the displacement of the wedge when the block meets the pulley. Assume wedge is sufficiently long so that man does not fall down :
