Question: Two long, parallel wires are attracted to each other by a force per unit length of 320 N/m when they are separated by a vertical

Two long, parallel wires are attracted to each other by a force per unit length of 320 μN/m when they are separated by a vertical distance of 0.500 m. The current in the upper wire is 20.0 A to the right. Determine the location of the line in the plane of the two wires along which the total magnetic field is zero.
