Coulomb’s law states that the electrical force between two-point charges varies directly as the product of the charges and inversely as the square of the distance between them. If the electrical force between two-point charges 25x10^-9 coulombs and 75x10^-9 coulombs and 0.03 meters apart is 0.019N, find the electrical force between two-point charges 30x10^-9 coulombs and 120x10^-9 coulombs and 0.10 meters apart.

Coulomb’s Law

Coulomb's law states that the attraction or repulsion force between two charged things is proportional to the product of their charges and inversely proportional to the square of their distance. It has an effect along the line that connects the two-point charges.
