Question

the electric field at a point near an infinite thin sheet of charged conductor is

Answer 1

Bar magnet...................

Answer 2

Given:

Infinite thin charged sheet

To Find:

The electric field near it. E =?

Calculation::

There two sides of the thin sheet. The flux through the sheet is:

Use Gauss Law:

$\int E.ds = \frac{q}{\epsilon _o} \\ES+ES=\frac{q}{\epsilon _o} \\2ES=\frac{q}{\epsilon _o} \\E=\frac{q}{2S\epsilon _o} \\E=\frac{\sigma}{2\epsilon_o}$
