A constant horizontal force (F) is applied at the vertex A of an equilateral triangular wedge ABC of mass M and side length AB=BC=CA= , placed on a rough horizontal surface as shown in the figure. Even after the application of force F the wedge remains stationary. Calculate the torque of normal reaction acting between the wedge and the floor about the vertex B.
