For these situations, the electric field can for example be a constant on the surface of the integration and can be taken out of the integral defined above
Common Problem Solutions and Notes
When an external electric field is applied to a dielectric material this material becomes polarized, The electric polarization P(r') is defined as the dipole moment per unit volume The constant χe is the electric susceptibility of the medium
