A rogue black hole with a mass 39 times the mass of the sun drifts into the solar system on a collision course with earth.

A) How far is the black hole from the center of the earth when objects on the earth's surface begin to lift into the air and "fall" up into the black hole? Give your answer as a multiple of the earth's radius.
