Question

Electric field intensity due to an infinite plane sheet of charges.

Answer 1

Explanation:

Electric Field: Sheet of Charge

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 . ... The resulting field is half that of a conductor at equilibrium with this surface charge density.

Answer 2

The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward.
