Solution

The correct option is A y = x
$\frac{μ_{0}}{4 π} \frac{2 l}{y} - \frac{μ_{0}}{4 π} \frac{2 l}{x} = 0 \Rightarrow y = x$

The correct option is A y = xμ04π2ly−μ04π2lx=0⇒y=x

The correct option is A y = x
$\frac{μ_{0}}{4 π} \frac{2 l}{y} - \frac{μ_{0}}{4 π} \frac{2 l}{x} = 0 \Rightarrow y = x$
