On the way to the moon, the Apollo astro- nauts reach a point where the Moon's gravi-
tational pull is stronger than that of Earth's.
Find the distance of this point from the
center of the Earth. The masses of the
Earth and the Moon are 5.98 x 1024 kg and
7.36 x 1022 kg, respectively, and the distance
from the Earth to the Moon is 3.84 x 108 m.
