[QUE/EM-05005] --- EM-PROBLEM --- Point charge and two dielectric media separated by a plane boundary

Consider a point charge \(q\)  embedded in a semi-infinite dielectric medium of dielectric ) constant  \(\epsilon_1\), and located a distance  from a plane interface that separates the first medium from another semi-infinite dielectric medium of dielectric constant  \(\epsilon_2\). Suppose that the interface coincides with the plane. Find the electric field everywhere if the distance of the point charge from the interface is \(d\).
