A uniform cube of side a and mass m rests on a rough horizontal table. A horizontal force mn is applied normal to one of the faces at a point that is directly below the centre of face, at a height 3a/4 above the base. The minimum value of F for which the cube begins to tilt about the edge is? (Assume that the cube does not slide).

Taking moments abut point O :
Moment of N (normal reaction) and f (force of friction) are zero. In critical case normal will pass through O. To tip about the edge, moment of F should be greater than moment of mg or,
