Two long, parallel, current$-$carrying wires lie in an $\backslash ($ x y $\backslash )-$plane. The first wire lies on the line $\backslash ($ y$=0\mathrm{.}400\backslash$mathrm$\{$~m$\}\backslash )$ and carries a current of $28\mathrm{.}0$ A in the $\backslash (+$x $\backslash )$ direction. The second wire lies along the $\backslash ($ x $\backslash )-$axis. The wires exert attractive forces on each other, and the force per unit length on each wire is $\backslash (295\backslash$mu $\backslash$mathrm$\{$~N$\}/\backslash$mathrm$\{$m$\}\backslash ).$ What is the $\backslash ($ y $\backslash )-$value $($in m $)$ of the line in the $\backslash ($ x y $\backslash )-$plane where the total magnetic field is zero?
