Three long wires all lie in an xy plane parallel to the x axis. They intersect the y axis at the origin, y = d, and y = 2d, where d = 9.1 cm. The two outer wires each carry a current of 3.6 A in the positive x direction. What is the magnitude of the force on a 3.4 m section of either of the outer wires if the current in the center wire is 2.6 A(a) in the positive x direction and (b) in the negative x direction?
