In the figure shown, the tension in Block B lying on a table weighs W. The coefficient of static friction between the block and the table is μ. Assume that the cord between B and the knot is horizontal. The maximum weight of the block A for which the system will be stationary is: the horizontal cord is 30 N. The weight of the body B is
