Wire 1 and Wire 2 are fixed parallel to each other at a separation distance of \(4d\). Wire 1 carries a current of \(3I\) directed into the page, while Wire 2 carries a current of \(I\) directed out of the page. Point \(P\) lies on the line connecting the two wires at a distance \(d\) from Wire 1. Which of the following correctly gives the magnitude of the net magnetic field \(B_{\text{net}}\rangle\) at point \(P\), and the ratio \(F_1 / F_2\) of the magnetic force per unit length exerted on Wire 1 to that on Wire 2?
