    Gauss's law Law Proof
Click For Summary
SUMMARY

This discussion focuses on the proof and derivation of Gauss's Law, particularly its relationship with Coulomb's Law and the Divergence Theorem. Participants clarify that while Gauss's Law can be derived from Coulomb's Law, it is not rigorously proven for all closed surfaces without additional assumptions. The Divergence Theorem is highlighted as a tool for transitioning between the integral and differential forms of Gauss's Law, but it does not serve as a direct proof. The conversation emphasizes the importance of understanding the underlying concepts of electric flux and the inverse-square law in three-dimensional space.

PREREQUISITES
  • Understanding of Gauss's Law and its applications in electromagnetism.
  • Familiarity with Coulomb's Law and its mathematical formulation.
  • Knowledge of the Divergence Theorem and its role in vector calculus.
  • Basic concepts of electric flux and inverse-square relationships in physics.
NEXT STEPS
  • Study the mathematical derivation of Gauss's Law using the Divergence Theorem.
  • Explore detailed explanations of electric flux in various electromagnetic textbooks.
  • Learn about the applications of the Divergence Theorem in different physical contexts.
  • Investigate the relationship between electric field intensity and power distribution in three-dimensional space.
USEFUL FOR

Students of physics, particularly those studying electromagnetism, educators seeking to explain Gauss's Law, and researchers interested in the mathematical foundations of electrostatics.

I'm fairly sure this can be done with lagrangians as long as you are comfortable with the jump from lagrangians to lagrangian densities.
