An infinite line of charge with uniform line charge density of $1 \mathrm{C} {\mathrm{m}}^{-1}$ is placed along the $\mathrm{y}$-axis. A charge of $1\mathrm{C}$ is placed on the $\mathrm{x}$-axis at a distance of $d=3 \mathrm{m}$ from the origin. At what distance $\left(r\right)$ from the origin on the $\mathrm{x}$-axis, the total electric field is zero.$N$ (Assume $0<r<d$)
