  This paper demonstrates a relationship between mass and charge through
explicit construction of exact Einstein-Maxwell spacetimes by embedding the
Schwarzschild and Kerr instantons in 5 dimensions. It is shown further how by
varying only the mass of an object, its electric field or apparent "charge"
changes, while making it possible for two different mass values to yield the
same electric field strength. The 5-dimensional solution, however, reduces to
the familiar Coulomb limit $1/r^2$ for large distances.
