Miniature black holes. Left over from the big-bang beginning of the universe, tiny black holes might still wander through the universe. If one with a mass of 1.00 101 [kg] (and a radius of only 1.00 10-16 [m]) reached Earth, at what distance from Earth's 9.81 [m/s2]) will its gravitational pull be enough to make objects resting on Earth's surface weightless? (G= 6.67 10-11 [m kg-.s-2]) surface (g =
