The earth attracts a large flying bug toward its center with a force of 0.10 Newtons. With what force does the bug attract the earth itself?

1. 1.0 N
2. 0.10 N
3. Trillions of Newtons
4. 10 N
5. We need the mass of the bug.
6. Zero; the earth attracts the bug, not the other way around.
7. A very, very, very small fraction of a Newton, since the bug’s mass is negligible compared to the earth’s mass
