A block of mass m =2 kg is placed on a plank of mass M = 10 kg, which is placed on a smooth horizontal plane as shown in the figure. The coefficient of friction between the block and the plank is `mu=(1)/(3)`. If a horizontal force F is applied on the plank, then the maximum value of F for which the block and the plank move together is `(g=10m//s^(2))`
