A long wire carrying a 6.0 A current perpendicular to the xy -plane intersects t

Question

A long wire carrying a 6.0 A current perpendicular to thexy-plane intersects the x-axis at x =-2.0cm. A second, parallel wire carrying a 3.5 Acurrent intersects the x-axis at x =+2.0cm. At what point on the x-axis is themagnetic field zero if the two currents are in the samedirection? At what point on the x-axis is themagnetic field zero if the two currents are in oppositedirections?
