A Long Wire Located at Z = 0 Carries Current

A long wire located at Z = 0 carries current i₁ = 3.00 A to the right as shown.A second long wire located a distance d = 0.240 m above the first wire carries a current i₂ = 1.10 A to the left as shown.Where in the Z direction (in m) does the magnetic field from the two wires sum to zero?

A) 0.285
B) 0.379
C) 0.504
D) 0.670
E) 0.892
