A uniform cube of side l and mass M rests on a rough horizontal table. A horizontal force F is applied normal to one of the faces at a point that is directly above the center of the face at a height 3l/4 above the base. Assuming that the cube may tip about an edgewithout slipping find the angular acceleration of the cube when F is equal to

(a) mg/3

(b) mg
