Physics - Cavendish did his experiment using lead spheres.

Cavendish did his experiment using lead spheres. Suppose he had replaced the lead spheres with copper spheres of equal mass. Would his value of G be the same or different? Explain.

AnswerIt would be the same, because the same value of G has been used successfully to describe the attraction of bodies having diverse chemical compositions: the Sun (a star), the planets, and satellites.
