Question

A long wire carrying IA = 4.0 A  of current perpendicular to the xy-plane intersects the x-axis at x=−2.0cm . A second, parallel wire carrying IB = 3.5 A  of current intersects the x-axis at x=+2.0cm . (As illustrated in the figure, the two currents are either into or out of the page.)

At what point on the x-axis is the magnetic field zero if the two currents are in opposite directions?
