Quizplus · Accepted Answer

Equation A is Coulomb's law, which states that the electric field from a point charge is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance from the charge. This equation can be derived using a symmetry argument based on the inverse square law, which states that the intensity of the electric field from a point source decreases with the square of the distance from the source.
