Three long, straight, parallel wires lie in the same plane as shown. Wire 1 is fixed at position \(x = 0\) carrying current \(I_0\) directed out of the page, and Wire 3 is fixed at position \(x = d\) carrying current \(4I_0\) directed out of the page. Wire 2 carries current \(I_2\) directed into the page and is placed between Wire 1 and Wire 3 at an equilibrium position \(x\) where the net magnetic force on Wire 2 is zero. In terms of \(d\), what is the equilibrium position \(x\) of Wire 2, and what is the direction of the net magnetic force on Wire 2 if it is displaced slightly toward Wire 3?
