Question

The surface charge density of a thick metal plate is sigma. The electric field near the surface is

Answer 1

Answer:

б/ε is the electric field per unit area on the surface

Explanation:

The electric field on the surface is twice the electric field of a non-conductor.

The electric field inside a conducting plate is always zero same that of sphere or ball.

Now, E=б/2ε+б/2ε=б/ε

Charge on one side of metal plate(thick) =б/2ε

Thus, as the surface charge of the metal plate is σ hence the electric field on the surface is б/ε.
