Static case of Maxwell's law for electricity only.
Is implied by Gauss' law if <Maxwell's equations>: https://physics.stackexchange.com/questions/44418/are-the-maxwells-equations-enough-to-derive-the-law-of-coulomb
The "static" part is important: if this law were true for moving charges, we would be able to transmit information instantly at infinite distances. This is basically where the idea of <field (physics)> comes in.
