The coefficient of friction between two surface is 0.2. The maximum angle of friction is

A is a 100kg block, and B is a 200kg block. As shown in figure the block A is attached to a string tied to a wall. The coefficient of friction between A and B is 0.2 and the coefficient of fricition between B and floor is 0.3. Then calculate the minimum force required to move the block B. (take g=10m//s^(2) ).

In the arrangement shown in figure, coefficient of friction between the two blocks is mu=1//2 . The force of friction acting between
