The Effect of Charge on the Properties of a Black Hole

If you throw an electron in, the black hole is going to gain a negative charge. But that charge doesn't just go away. Just before it fell into the black hole, there was an electric field there. It's sort of frozen in time from the last moment just before the electron crossed the event horizon. No more information can update it. The whole black hole now has an electric charge. And the super weird thing is think about what happens to the next electron. Say you have like a bag full of electrons you throw one in, now your black hole has anegative charge. Now electron number two, what happens to it? Well, it feels a gravitational attraction from the mass of
