A long wire carrying a 5.0 A current perpendicular to the xy-plane intersects the x-axis at x = -2.0 cm. A second, parallel wire carrying a 2.5 A current intersects the x-axis at x = 2.0 cm.

PART A
At what point on the x-axis is the magnetic field zero if the two currents are in the same direction?

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