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 
. 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 = 10 r n/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
B
40 N
assuming no slipping between m and M This means friction between the block and plank is
