176- According to the figure below, four thin, parallel, long current-carrying wires, carrying current $I$, are perpendicular to the page and fixed on the page. What are the coordinates of the origin where the magnetic field is zero? [Figure: Four wires arranged symmetrically; two wires going into the page at positions $(-d, yd)$ and $(yd, -yd)$, and two wires coming out of the page, with spacing $d$ and $yd$ along axes]
[(1)] $\dfrac{\mu_0 I}{4\pi d}$
[(2)] $\dfrac{\sqrt{5}\,\mu_0 I}{4\pi d}$
[(3)] $\dfrac{\sqrt{3}\,\mu_0 I}{4\pi d}$
[(4)] $\dfrac{\sqrt{2}\,\mu_0 I}{4\pi d}$
