pseudo force

The block of mass m is in equilibrium relative to the smooth wedge of mass M which is pushed by a horizontal force F. Find pseudo force acting on (a) m, (b)M as viewed by the observer sitting on the wedge. Will these pseudo forces (c ) equal and opposite, action reaction pairs? Explain.
