Three asteroids have exactly the same amount of mass. The distance from asteroid A to asteroid B is 300 km, the distance from asteroid B to C is 400 km, and the distance from C to A is 100 km. Between which two asteroids would the gravitational force be the largest?
**Weegy:** Two prominent theories of extinction are climate change and an asteroid hitting the Earth. **User:** Three identical satellites, X, Y, and Z are in outer space. The distance from satellite X to Y is 450 km, the distance from Y to Z is 600 km, and the distance from satellite Z to X is 450 km. Between which satellites will the force of gravity be the greatest?
