A uniform cube of side

a

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 centre of the face, at a height

3a/4

above the base. The minimum value of

F

for which the cube begins to tip about the edge is .... (Assume that the cube does not slide).
