Question
![An African elephant is walking along when a mini-black hole suddenly appears
directly above him. The mass of the black hole is so great that its gravity is able
to lift the elephant from the Earth. How close must the mini-black hole be to the
elephant's center of mass in order to just overcome the downward pull of Earth's
gravity? (Treat the mass of the elephant as if it's concentrated at the elephant's
center.
Mass of Earth ME = 6.97 x 1024 kg
Mass of mini-black hole MBH = 4.17 x 1012 kg
Radius of Earth RE = 6.40 x 106 meters
