Abstract

Expressions for polarizations of dielectric sphere with bound surface charges are founded in electrostatic approximation. Cases of uniform and symmetrical distributions of charges and systems of N point charges are considered. It is shown that perturbed potential in the case of a constant external electrostatic field is represented in form of two terms. In the case of a system of point charges is observed multipole polarizability
