No, I was just trying to envision the event horizon for a particle of the *same* charge as the black hole, positive or negative. The electrical repulsion would tend to frustrate the gravitational attraction.
Yeah, thought so.
A charged-particle would be repulsed by a like-charged Black Hole. Conceivably, one could "float" just outside the Event Horizon.
A few hundred pounds of electrons on the Moon and a few hundred pounds of electrons on the Earth would suffice to totally compensate for the gravitational attraction between the Earth and Moon - that's how powerful the electrostatic charge is.
If a spinning Black Hole can be oblate (flattened at the poles), could a charged Black Hole be polar (i.e. have measurable differences, from place to place over its "surface," in charge)?
