Two infinite planes each with uniform surface charge density $\displaystyle +\sigma$ are kept in such a way that the angle between them is $\displaystyle 30$°. The electric field in the region shown between them is given by :
Official answer
(4)
$\displaystyle \frac{\sigma}{2 \epsilon_0}\left[\left(1-\frac{\sqrt{3}}{2}\right) \hat{y}-\frac{\hat{x}}{2}\right]$
