Here is the metric for an uncharged non-rotating black hole:

Here is the metric for a charged non-rotating black hole:
http://en.wikipedia.org/wiki/Reissner-Nordström_black_hole
Note that this is the same as plugging M* = M - Q2/2r into the Schwarzschild metric.
My question is: If there is energy in the electric field of a charged particle, why doesn\'t this increase the effective mass?
Is this true for any quantum \"charge\"? For instance, if the black hole has excess \"weak charge\" or \"color\", does this decrease the radius of its event horizon/effective mass?
