Question

In the figure, a very large plane sheet of positive charge is shown. $P_1$ and $P_2$ are two points at distance I and 2l from the charge distribution. If $s$ is the surface charge density, then the magnitude of electric fields $E_1$ and $E_2$ at $P_1$ and $P_2$ respectively are :

Select the correct option:

A

$E_1=\sigma / \varepsilon_0, E_2=\sigma / 2 \varepsilon_0$

B

$E_1=2 \sigma / \varepsilon 0, E_2=\sigma / \varepsilon 0$

C

$E_1=E_2=\sigma / 2 \varepsilon_0$

D

$E_1=E_2=\sigma / \varepsilon 0$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

As the sheet is very large $\vec{E}$ is independent of distance from it. Thus $\mathrm{E}_1=\mathrm{E}_2=\frac{\rho}{2 \varepsilon_0}$
