The four conductive wires in the figure are parallel to each other and very long compared to the distance between them. a) Calculate the value and direction of current Iz so that the resulting force on current I is zero. 40 A 40 A (0,0.2) b) Calculate the resulting force per unit length on current 1, when the direction of current Iz is inverted and its value is unity. (0.6.0) (1.0) (0.-0.2) NOTE: The coordinates shown in the figure are expressed in meters. Define precisely all the physical quantities used. In mathematical developments clearly justify the step
