Question:medium
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 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 topple on an edge is (assume the cube does not slide):

Show Hint
For toppling problems, always take moments about the edge of rotation.
