  Approximate solutions representing the gravitational-electrostatic balance of
two arbitrary point sources in general relativity have led to contradictory
arguments in the literature with respect to the condition of balance. Up to the
present time, the only known exact solutions which can be interpreted as the
non-linear superposition of two spherically symmetric (Reissner-Nordstrom)
bodies without an intervening strut has been for critically charged masses,
$M^2_i = Q^2_i$. In the present paper, an exact electrostatic solution of the
Einstein-Maxwell equations representing the exterior field of two arbitrary
charged Reissner-Nordstrom bodies in equilibrium is studied. The invariant
physical charge for each source is found by direct integration of Maxwell's
equations. The physical mass for each source is invariantly defined in a manner
similar to which the charge was found. It is shown through numerical methods
that balance without tension or strut can occur for non-critically charged
bodies. It is demonstrated that other authors have not identified the correct
physical parameters for the mass and charge of the sources. Further properties
of the solution, including the multipole structure and comparison with other
parameterizations, are examined.
