I need to know the correct expression for the Lorentz force on a relativistic particle in an EM field, in cgs units, in terms of vector potential A and scalar potential phi, to prove that a given Lagrangian produces the correct equations of motion. I don't need it in covariant form with tensors and all of that because we haven't learned that yet. Thanks everyone.(adsbygoogle = window.adsbygoogle || []).push({});
