The coefficient of friction between block A of mass m_(1)=5kg and block B of mass m_(2)=10 kg is mu_(2)=0.5 . There is no friction froce between block B and fixed horizontal surface. A force of 300N acts on block B in horizontal direction and a horizontal force of magnitude F acts on block A as shown , both towards right. Initially there is no relative motion between the blocks. The minimum value of F such that relative motion starts between A and B is :
