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 3.5 1011 kg (and a radius of only 1.0 10-14 m) reached Earth, at what distance from your head would its gravitational pull on you match that of Earth's?

...I'm not sure how to go about solving this...
