As you walked on the moon, the earth's gravity would still pull on you weakly and you would still have an earth weight. How large would that earth weight be, compared to your earth weight on the earth's surface? (Note : The earth's radius is 6378km and the distance seperating the centers of the earth and moon is 384,400 kilometers.)
