Hint: for part I use G = 6.67 times 10 to the
negative 11. for part II, you don’t need to
do the full calculation, you can just use your
knowledge of how force of gravity depends on
mass and separation distance.
Compare the gravitational force on a 49 kg
mass at the surface of the Earth (with ra-
dius 6.4 × 106 m and mass 6 × 1024 kg) with
that on the surface of the Moon with mass
1
81.3
ME and radius 0.27RE.
What is the force on the Earth?
Answer in units of N.

Your 1 and 81.3 makes no sense to me.
