Q.
As shown in the figure, a point charge $q_{1}=+1 \times 10^{-6} C$ is placed at the origin in $x-y$ plane and another point charge $q_{2}=+3 \times 10^{-6} C$ is placed at the co-ordinate $(10,0)$. In that case, which of the following graph(s) shows most correctly the electric field vector in $E_{x}$ in $x$-direction ?
