does coulomb's law govern magnetic attraction and replusion also?
thanks

Coulomb's law is a fundamental law of physics that describes the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The units of Coulomb's law are newtons (N) for force, coulombs (C) for charge, and meters (m) for distance. In the SI system, the constant of proportionality is represented by k=9x10^9 Nm^2/C^2.
Coulomb's law is an example of the inverse square law, which states that the strength of a physical quantity is inversely proportional to the square of the distance from the source. In the case of Coulomb's law, the strength is the electrostatic force between two charges, and the source is the two charges themselves.
Yes, Coulomb's law can be extended to calculate the force between multiple charges using vector addition. The total force on a given charge is the vector sum of the individual forces from each charge.
Coulomb's law is closely related to electric fields, as the force between two charges can be described in terms of the electric field created by one of the charges. The electric field is a vector quantity that describes the strength and direction of the force experienced by a test charge placed in the field. Coulomb's law is essentially the mathematical expression of the electric field created by a point charge.
