Comment on "Dynamics of a Charged Particle"
Igor V. Sokolov
TL;DR
This paper critiques and clarifies the validity conditions of a charged particle dynamics equation originally derived by Rohrlich, aligning it with classical field theory results after correction.
Contribution
It identifies and corrects the validity condition of Rohrlich's equation, reconciling it with established classical field theory equations.
Findings
The original validity condition is inapplicable as stated.
After correction, the equation matches classical theory results.
Clarifies the relationship between Rohrlich's equation and Landau-Lifshitz equations.
Abstract
The equation derived by F.Rohrlich (Phys.Rev.E 77, 046609 (2008)) reproduces Eq.(76.3) from the Landau and Lifshitz book (The Classical Theory of Fields). The new validity condition for this equation is inapplicable as it is, but once fixed it coincides with Eqs.(75.11-12) in the cited book.
