There are two long straight wires with current in opposite directions. The first wire carries a current of 0.19 A and passes through the xy-plane at the origin, while the second wire carries a current of 0.68 A and passes through the xy-plane at the coordinate (7.04 m,0). Where along the x-axis is the net magnetic field due to the two wires equal to zero? Give your answer as an x-coordinate in units of m. Note: The locations on the positive x-axis have positive values while the locations on the negative x-axis have negative values.
