A nonconducting sheet of large surface area and thickness d contains 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 `0ltxltltd`.

Text Solution

Verified by Experts

We know `oint E. ds = q/ epsilon_0`
` E. x. d = (rho(x^2) d / epsilon_0), E= (rho x / epsilon_0)` .
