Derivation of coloumbs law without Gauss's law

Click For Summary

Discussion Overview

The discussion revolves around the derivation of Coulomb's law without relying on Gauss's law. Participants explore the historical context and the relationship between these two fundamental concepts in electrostatics.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant notes that Coulomb's law is often derived using Gauss's law, leading to confusion about which came first.
  • Another participant states that historically, Coulomb's law was established first as an experimental formula and was not derived from any other equation.
  • A different viewpoint suggests that from a modern perspective, the differential Maxwell equations are the fundamental laws, with Coulomb's law emerging as a special case through the Green's function of the Laplacian.
  • One participant argues that physical laws do not require proof, suggesting that Gauss's law serves as a technique to determine the electric field rather than a foundational derivation of Coulomb's law.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of deriving Coulomb's law from Gauss's law and the historical precedence of these laws. There is no consensus on a singular approach or understanding.

Contextual Notes

Participants acknowledge the experimental nature of Coulomb's law and the theoretical framework provided by Maxwell's equations, but there are unresolved questions regarding the derivation and interdependence of these laws.

Whenever I try searching on how coloumbs law is derived Gauss's law is always used,for this reason when I search for Gauss's law it is always derived from coloumbs law :frown:.could you guys guys help me out by telling me which camfirst and how it was derived
  • Coloumbs law- F=Q1Q2/r2ε
  • Gauss's law-∫E.DA=Q/ε
 
Physics news on Phys.org
Historically, Coloumb's law came first but it wasn't derived from any other equation. Its an experimental formula. See here!
 
From a modern point of view, however, it's clear that the differential Maxwell equations are the fundamental laws governing electromagnetic phenomena, and electrostatics is the special case of having no current densities and a static situation. Coulomb's Law is then found via the Green's function of the Laplacian.
 
Thanks guys
 
for any physical law there is no need of its proof..coz most of law is natural in physics...gauss law is the technic to find the electric field
