What are the limitations of coulomb's law?

Answer 1

coulombs law is valid if the average number of solvent molecules between two interacting charges is large enough that the properties of the micro region of solvent can be expected to b similar to that of the bulk solvent.

Answer 2

One limitation of Coulomb's law is that it only applies to point charges, so it may not accurately predict the behavior of complex charge distributions. Additionally, Coulomb's law assumes the charges are at rest, so it does not account for relativistic effects at high speeds. Finally, Coulomb's law does not take into account quantum mechanical effects that are relevant on atomic and subatomic scales.
