A uniform cube of mass M and side a is placed on a frictionless horizontal surface. A vertical force F is applied to the edge as shown in figure. Match the Column I with Column II. Column IColumn II(A)(p)Cube will move up.(B)(q)Cube will not exhibit motion.(C)(r)Cube will begin to rotate and slip at A.(D)(s)Normal reaction effectively at a/3 from A, no motion.

The correct answer is C. From figure, moment of force F about A, anticlockwise. Moment of weight Mg of cube about A. Clockwise. The cube will not exhibit any motions, If Or The cube will rotate only, when If we assume that normal reactions is effective at a/3 from A, then block would turn if When there will be no motion. Hence, we conclude
