A particle of charge -e and mass m moves under a coulomb

A particle of charge -e and mass m moves under a coulomb attraction round a fixed charge +2e. Show that the allowed energies include both discrete and continuous values and that the former may be written in the form RchZ2 n2 What changes need to be made in the energy formula for the positive charge instead of being fixed is free to move and has a mass M?
