Box A weighs 50 N and rests on a table. A rope thatconnects boxes A and B drapes over a pulley so that box Bhangs above the table, as shown in the figure. The pulleyand rope are massless, and the pulley is frictionless.BAWhat force nj does the table exert on box A if box Bweighs 20 N? Assume that the positive directionni =Nis upwards.What force n2 does the table exert on box A if box Bweighs 40 N? Assume that the positive directionn2 =Nis upwards.What force n3 does the table exert on box A if box Bn3 =Nweighs 60 N? Assume that the positive directionis upwards.

When the box A rests on the table, sum of all the forces applied to it is zero. That is, W1-W2-N=0
