Question

A non-conducting sheet of large surface area and thickness d contains a uniform charge distribution of density rho. Find the electric field at a point P inside the plate, at a distance x from the central plane. Draw a qualitative graph of E against x for 0 < x < d.

Answer 1

Given A non-conducting sheet of large surface area and thickness d.

Uniform charge distribution of density $\rho$

$From the Gauss law$

$\closed\int\limits^a_b {E} .da = \frac{charge inclosed}{e}$

$Charge enclsed = \rho*Area$

$E.A= \frac{\rho*A}{e}$

$\therefore E=\frac{\rho}{e}$

The electric field at a point P inside the plate, at a distance x from the central plane  $\frac{\rho_x}{e}$
