Problem
Four identical point charges, each of magnitude +Q, are placed at the corners of a square of side length a. The space is entirely filled with a uniform dielectric material of relative permittivity κ. Derive a simplified symbolic expression for the electric potential at the center of the square in terms of Q, a, κ, and fundamental constants.
