Physics 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 tilt about the edge is (assume that the cube does not slide) (a) mg/4 (b) 2mg/3 (c) 3mg/4 (d) mg Ans. b Read More
