2) There are two wires at the bottom corners of the square (wire A and B). A third wire is placed at the midpoint at the top side of the square (wire C). The sides of the square are 10 cm. The current in each wire is 2 A. The direction of the current in each wire is indicated on the figure. Find the net force per unit length on wire C. Express your answer in unit vector notation.
