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.
