The figure on the side shows the cross-sectional view of three long conducting wires parallel and perpendicular to the plane of the screen. The three are covered by electric currents of 1.50 A, whose conventional directions are indicated in the figure. The distance between the wires and the point P is equal to 5.0 cm.
