Four blocks are arranged on a smooth horizontal surface as shown. The masses of the blocks are given (see the diagram). The coefficient of static friction between the top and the bottom blocks is mu_(s) . What is the maximum value of the horizontal force F, applied to one of the bottom blocks as show, thilt makes all four blocks move with the same acceleration ?
