Coulomb's Law
We explain Coulomb's law both qualitatively as well as mathematically. We examine this law even further by doing an example problem where we solve for the electric force and field strengths. The properties of an electric field are also discussed.

Vocabulary
Coulomb’s Law - law devised by Charles Coulomb that explains the factors that affect contribute to the electrostatic force; is equal to Coulomb’s constant times the magnitude of two charges divided by the distance between the charges, squared. electric field (E) - a region around a charged particle or charged object within which a force is exerted on other charged particles or charged objects. electrostatic force (FE) - one of the four fundamental forces of the universe; the attraction and repulsion of particles based on their electrical charges; is equal to Coulomb’s constant times the magnitude of two charges divided by the distance between the charges, squared. |
