Bhí dlí Coulomb riachtanach d’fhorbairt [[Leictridinimic|theoiric an leictreamaighnéadais]], b’fhéidir fiú a phointe tosaigh, toisc go raibh sé indéanta méid an luchta leictreachais a phlé go ciallmhar. <ref>{{cite book |last1=Roller |first1=Duane |last2=Roller |first2=D.H.D.|date=1954 |title=The development of the concept of electric charge: Electricity from the Greeks to Coulomb |url=https://archive.org/details/developmentofcon0000roll|url-access=registration |location=Cambridge, MA |publisher=[[Harvard University Press]] |page=[https://archive.org/details/developmentofcon0000roll/page/79 79] }}</ref>

{{ Translation: It follows therefore from these three tests, that the repulsive force that the two balls — [that were] electrified with the same kind of electricity — exert on each other, follows the inverse proportion of the square of the distance.|author=Coulomb (1785b) [https://books.google.com/books?id=by5EAAAAcAAJ&pg=PA578#v=onepage&q&f=false "Second mémoire sur l’électricité et le magnétisme,"] ''Histoire de l’Académie Royale des Sciences'', pages 578–611}}

Coulomb also showed that oppositely charged bodies obey an inverse-square law of attraction.</ref>
