Let $\displaystyle \sigma$ be the uniform surface charge density of two infinite thin plane sheets shown in figure. Then the electric fields in three different region $\displaystyle E_I, E_{I I}$ and $\displaystyle E_{\text {III }}$ are:
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle \vec{E}_I=-\frac{\sigma}{\epsilon_0} \hat{n}, \vec{E}_{I I}=0, \vec{E}_{I I I}=\frac{\sigma}{\epsilon_0} \hat{n}$
