Coulomb's Law is a fundamental law of physics that describes the electrostatic interaction 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.
Repulsion is the force that pushes two charged particles with the same type of charge away from each other. According to Coulomb's Law, the magnitude of repulsion increases as the charges of the particles increase and decreases as the distance between them increases.
Coulomb's Law is applicable in various real-world situations, such as in determining the force between two electrically charged objects, calculating the strength of electric fields, and understanding the behavior of charged particles in atoms and molecules.
Coulomb's Law and Newton's Law of Gravitation are both inverse-square laws that describe the force between two objects. However, Coulomb's Law deals with the electrostatic force between charged particles, while Newton's Law of Gravitation deals with the gravitational force between massive objects.
The constant k, also known as the Coulomb constant, is a proportionality constant that relates the force between two charged particles to their charges and the distance between them. Its value is 8.99 x 10^9 Nm^2/C^2, and it is essential in calculating the magnitude of the force between charged particles in Coulomb's Law.
