Question 2

Would you be richer if you had a hunk of gold whose weight is 1 newton on the moon, or one whose weight is 1 newton on Earth, and why?

  B) 1 newton on the moon, because then the gold's mass would be larger.
  C) 1 newton on Earth, because then the gold's mass would be larger.
  D) 1 newton on Earth, because then the gold's weight on Earth would be larger.
  E) It wouldn't make any difference, because the amount of actual gold would be the same in both cases.
