Which force is primarily responsible for keeping planets in orbit around the sun?

  • AMagnetic force
  • BGravitational force
  • CElectrostatic force
  • DNuclear force
Permalink
Correct Answer: Option B — Gravitational force
Explanation: Gravitational force between the sun and planets keeps them in stable orbits by continuously pulling them toward the sun while their forward momentum prevents them from falling in.
