The gravitational forces two bodies exert on each other have magnitudes that are:
AThe same on each
BThe sum of each
CThe half of each
DThe tenth of each
Answer & Solution
Correct answer: A. The same on each
1. Gravitation acts between a pair, not from one body onto another.
2. The Earth pulls the Moon and the Moon pulls the Earth.
3. The magnitude of the force is the same on each.
4. That is consistent with the third law of motion.
