Two point charges $\displaystyle \mathrm{q}_1(\sqrt{10} \mu \mathrm{C})$ and $\displaystyle \mathrm{q}_2(-25 \mu \mathrm{C})$ are placed on the $\displaystyle x$-axis at $\displaystyle x=1 \mathrm{~m}$ and $\displaystyle x=4 \mathrm{~m}$ respectively. The electric field (in $\displaystyle \mathrm{V} / \mathrm{m}$ ) at a point $\displaystyle y=3 \mathrm{~m}$ on $\displaystyle y$-axis is, $$\left[\text { take } \frac{1}{4 \pi \epsilon_0}=9 \times 10^9 \mathrm{Nm}^2 \mathrm{C}^{-2}\right] $$
