A small block of mass 1kg is placed over a plank of mass 2kg. The length of the plank is 2 m. coefficient of friction between the block and the plnak is 0.5 and the ground over which plank in placed is smooth. A constant force F=30N is applied on the plank in horizontal direction. the time after which the block will separte from the plank is `(g=10m//s^(2))`

A block of mass 1 kg is placed over a plank of mass 2 kg. The length of the plank is 2m. Coefficient of friction between the block and the plank is 0.5 and the ground over which plank is placed is smooth. A constant force F = 30 N is applied on the plank is horizontal direction. The time after which the block will separate from the plank is 73xx10^(-x)S the value of x is : (g = 10 m//s^(2))

A plank of mass 2 kg and length 1 m is placed on horizontal floor.A small block of mass 1 kg is placed on top of the plank , at its right extreme end .The coefficient of friction between plank and floor is 0.5 and that between plank and block is 0.2 . If a horizontal force = 30 N starts acting on the plank to the right ,the time after which the block will fall off the plank is (g = 10 ms^(-2))
