Rotation: Torque

Q- A block of weight 150 lb is placed on a rough horizontal surface and a horizontal force P = 60 lb is acting on it as in figure. The friction is sufficient to prevent sliding. Find the horizontal distance between the line of action of the weight of the block and the normal reaction of the surface.
