Electric field

Question

Two large parallel sheets A and B have charge densities $+ 2 nC / m^{2}$ and $- 5 nC / m^{2}$ . If P is a point in space outside the sheets. Then electric field at P is

Moderate

Solution

$\vec{E_{P}} = \vec{E_{A}} + \vec{E_{B}} = \frac{+ 2 \times 10^{- 9}}{2 \in_{0}} \hat{i} + \frac{(- 5) \times 10^{- 9}}{2 \in_{0}} \hat{i} = - \frac{3 \times 10^{- 9}}{2 \times 8 .85 \times 10^{- 12}} \hat{i} \frac{V}{m}$
$∴ E_{P} = 169 .5 \frac{V}{m}$
