Coulomb's 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.
Coulomb's Law is directly related to electric fields. Electric fields are created by charged particles and the strength of the field is determined by the charge of the particle and its distance from the point of observation. The direction of the electric field is the same as the direction of the force that a positive test charge would experience if placed in the field.
The SI unit of charge used in Coulomb's Law is the Coulomb (C). One Coulomb is defined as the amount of charge that passes through a conductor in one second when there is a constant current of one ampere (A).
The magnitude of the charges has a direct impact on the force between them. According to Coulomb's Law, the force between two charged particles increases as the magnitude of the charges increases. This means that the larger the charges, the stronger the force between them.
No, Coulomb's Law can be applied to any charged particles, whether they are point charges or not. However, for non-point charges, the distance between the particles must be much larger than their size in order for the law to be accurate. This is because Coulomb's Law assumes that the charges are concentrated at a single point.
