An difríocht idir athruithe ar: "Dlí Coulomb"

Is [[Dlí eolaíoch|dlí]] turgnamhach [[Fisic|fisice]] é '''Dlí Coulomb''', <ref name=":0">{{Cite book|last=Huray, Paul G., 1941-|url=https://www.worldcat.org/oclc/739118459|title=Maxwell's equations|date=2010|publisher=Wiley|isbn=978-0-470-54991-9|location=Hoboken, N.J.|pages=8, 57|oclc=739118459}}</ref> nó '''Dlí an Chearnfhaid Inbhéartaigh Coulomb''', a chainníochtaíonn ar an méid an fhórsa idir dhá cháithnín atá [[Lucht leictreach|luchtaithe go deimhneachleictreach]] agus nach bhfuil ag bogadh.

Deirtear sa dlí go bhfuil méid fhórsa leictreastatach an aomacháin nó an éartha idir dhá [[Lucht leictreach|phonclucht]] comhréireach go díreach le táirge méideanna na luchtanna agus comhréireach go hinbhéartach leis an fhad cearnaithe eatarthu.<ref name="1785a">Coulomb (1785) [https://books.google.com/books?id=by5EAAAAcAAJ&pg=PA569#v=onepage&q&f=false "Premier mémoire sur l’électricité et le magnétisme,"] ''Histoire de l’Académie Royale des Sciences'', pp. 569–577 — Coulomb studied the repulsive force between bodies having electrical charges of the same sign:{{quote|''Il résulte donc de ces trois essais, que l'action répulsive que les deux balles électrifées de la même nature d'électricité exercent l'une sur l'autre, suit la raison inverse du carré des distances.''
