Consider the system shown below A horizontal force F is applied to a block X of mass 8 ~kg such that the block Y of mass 2 ~kg adjacent to it does not slip downwards under gravity. There is no friction between the horizontal plane and the base of the block X . The coefficient of friction between the surfaces of blocks X and Y is 0.5 . Take acceleration due to gravity to be 10 ~ms ⁻² . The minimum value of F is
