Coulomb's Law is a fundamental law of physics that describes the electrostatic force between two charged particles. It states that the force of attraction or repulsion between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Electrons and protons are both charged particles, with electrons having a negative charge and protons having a positive charge. Coulomb's Law applies to them by determining the force of attraction or repulsion between them based on their charges and the distance between them.
According to Coulomb's Law, the force between electrons and protons decreases as the distance between them increases. This means that the force is stronger when the particles are close together and weaker when they are farther apart.
The unit of measurement for charge in Coulomb's Law is Coulomb (C). This is a measure of the amount of electric charge, with electrons having a charge of -1.602 x 10^-19 C and protons having a charge of +1.602 x 10^-19 C.
Coulomb's Law is closely related to the concept of electric fields. The force between two charged particles can be thought of as the result of an electric field created by one particle acting on the other. The strength of the electric field is determined by the charges and distance between the particles, and can be calculated using Coulomb's Law.
