Coulomb's law, also known as Coulomb's inverse-square law, is a fundamental law of physics that describes the electrostatic interaction between two charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The units of measurement for the electric force in Coulomb's law are Newtons (N). This is because force is defined as the product of mass and acceleration, and in the case of Coulomb's law, the force is acting on a charged particle due to the electric field.
Coulomb's law is directly related to the concept of electric fields. The force described in Coulomb's law is the force that acts on a charged particle due to the electric field created by another charged particle. The electric field is a measure of the force per unit charge at a given point in space.
The constant in Coulomb's law, also known as the Coulomb constant or the electric constant, has dimensions of meters per coulomb squared (m/C^2). This means that it represents the relationship between the strength of the electric force and the distance and magnitude of the charges involved.
When dealing with multiple charged particles, Coulomb's law can be extended to calculate the net force on a charged particle due to multiple other charged particles. This is done by summing up the individual forces between the charged particle and each of the other charged particles, taking into account the direction and magnitude of each force.
