In the arrangement shown in the figure mass of the block B and A are 2m and 8m respectively. Surface between B and floor is smooth. The block B is connected to block C by means of a pulley. If a whole system is released then the minimum value of mass of the block C so that the block A remains stationary with respect to B is (Co-efficient of friction between A and B is µ)-
