Question

2) (a) Show that the x-component of the Lorentz force, when written in terms of vector potentials as we did in class, can be expanded and then recast as o where U q-qA. Thus, show that Lagranges equations still hold so long as U is taken to have this form, and that the Lagrangian for a non-relativistic particle in an electric and magnetic field can be written as equation (7.104) in the text. (b) Show from this Lagrangian and the analysis in Section 7.8 that the H an electromagnetic field is for a charged particle in
