Question

what is the difference between gravitational force and electromagnetic force?

Answer 1

Gravitational force:
(1) The gravitational force is the force of mutual attraction between any two object by virtue of masses.
(2) These are the weakest force in nature.
(3) They operate over very long distances especially when the bodies are massive.

Electromagnetic force:
(1) The electromagnetic forces are the forces between charged particles.
(2) Electromagnetic forces are so much stronger as compared to gravitational forces.
(3) These forces may be attractive or repulsive depending on the nature of charges.
