Question

what is electric field due to a conductor plate of finite length have surface charge density sigma ?​

Answer 1

✔The net electric charge of a conductor resides entirely on its surface. (The mutual repulsion of like charges from Coulomb's Law demands that the charges be as far apart as possible, hence on the surface of the conductor.) 2. The electric fieldinside the conductor is zero.

Answer 2

Answer:

For an infinite sheet of charge, the electric field will be perpendicular to the surface. Therefore only the ends of a cylindrical Gaussian surface will contribute to the electric flux . In this case a cylindrical Gaussian surface perpendicular to the charge sheet is used.
