medium

Two infinite sheets of uniform charge density $+\sigma$ and $-\sigma $ are parallel to each other as shown in the figure. Electric field at the

points to the left or to the right of the sheets is zero.

midpoint between the sheets is zero.

midpoint of the sheets is $\sigma / \varepsilon_0 $ and is directed towards right.

$A$ and $C$ both

Solution

Electric field due to charge sheet for charge density $+\sigma$ is $E=\frac{+\sigma}{2 \epsilon_{0}}$ and for $-\sigma$ is $E=$$\frac{-\sigma}{2 \epsilon_{0}}$

outside the plates field is $E=\frac{+\sigma}{2 \epsilon_{0}}+\frac{-\sigma}{2 \epsilon_{0}}=0$

between the plates field is $E=\frac{\sigma}{2 \epsilon_{0}}+\frac{\sigma}{2 \epsilon_{0}}=\frac{\sigma}{\epsilon_{0}}$
