Query: On the interaction between two point electric charges   The general formula for the interaction potential between two point electric
charges which contains the lowest order corrections to the vacuum polarization
is derived and investigated. Analytical derivation of this formula is based on
the closed analytical expression for the Uehling potential obtained earlier.
Our analytical formula has the correct asymtotic behaviour at small and large
distances between two interacting electric charges. We also discuss a number of
problems which are of great interest in applications, e.g., vacuum polarization
corrections to the Coulomb scattering and cusp value between two electrically
charged particles. An original algebraic procedure developed in this study
allows one to determine consequtive corrections for vacuum polarization for
Coulomb systems.
