The drawing shows two perpendicular, long, straight wires, both of which lie in the plane of the paper. There are electric currents running in the wires in the directions shown in the drawing. In the drawing r₁= 44.1cmand r₂= 5.9cm. If the net magnetic fields at pointsAandB are 2.1 x 10^-5 T and 19.2 x 10^-5 T, respectively (both in the same direction), what is the current I2in the horizontal wire?
