Coulomb's Law

Coulomb's Law is a fundamental principle in electromagnetism that describes the force between two point charges. It states that the magnitude of the electrostatic force is directly proportional to the product of the charges' magnitudes and inversely proportional to the square of the distance between them. This law establishes an inverse-square relationship, meaning that if the distance between the charges is doubled, the force is reduced by a factor of four. The law applies to static charges and forms the basis for understanding interactions in electric fields.

Electrostatic Potential Energy

Electrostatic potential energy is the energy stored in a system of charges due to their positions relative to one another. This energy depends on the magnitude of the charges, the distance between them, and the sign of the charges. According to the principles derived from Coulomb's Law, the potential energy is inversely proportional to the distance separating the charged particles, meaning that as the distance increases, the potential energy decreases. The sign of the potential energy indicates the nature of the interaction: a negative value implies an attractive force between unlike charges, while a positive value implies a repulsive force between like charges.
