Question

Which charge configuration produces a uniform electric field? (a) point charge (b) uniformly charged infinite line (c) uniformly charged infinite plane (d) uniformly charged spherical shell​

Answer 1

$\large{\underline{\underline{\textsf{{\orange{Answer :- }}}}}}$

For an infinite uniformly charged infinite plane, the electric field only depends on the surface charge density of the plane so it is independent of the distance and hence it remains constant in space. So, an infinite uniformly charged plane generates a uniform electric field. Hence the correct choice is option (C).
