A long wire carrying a $5\mathrm{.}0$ AA current perpendicular to the xyxy$-$plane intersects the xx$-$axis at x$=2\mathrm{.}1$cmx$=2\mathrm{.}1$cm$.$ A second, parallel wire carrying a $2\mathrm{.}8$ AA current intersects the xx$-$axis at x$=+2\mathrm{.}1$cmx$=+2\mathrm{.}1$cm$.$ At what point on the xx$-$axis is the magnetic field zero if the two currents are in the same direction?
