In the arrangement shown in the figure mass of the block B and A are 2m,8m respectively and the floor is smooth. The block B is connected to block C by means of a pulley. If the whole system is released then the minimum value of mass of the block C so that block A remains stationary with respect to B is:
1.Co-efficient of friction between A and B is \(\mu \)
2.No friction between B and floor.
