The horizontally placed conductors of a single phase line operating at $50$ $Hz$ are having outside diameter of $1.6$ $cm$, and the spacing between centers of the conductors is $6$ $m$. The permittivity of free space is $8.854\times 10^{12}F/m$. The capacitance to ground per kilometer of each ... $4.2\times 10^{9}F$ $8.4\times 10^{9}F$ $4.2\times 10^{12}F$ $8.4\times 10^{12}F$

A steady current $I$ is flowing in the $x$ direction through each of two infinitely long wires at $y = ± \frac{L}{2}$ as shown in the figure. The permeability of the medium is $\mu_{0}$. The $\vec{B}$field at $(0,L,0)$ is $\frac{4\mu _{0}I}{3\Pi L} \hat{Z}$ $+\frac{4\mu _{0}I}{3\Pi L} \hat{Z}$ $0$ $\frac{3\mu _{0}I}{4\Pi L} \hat{Z}$
