(1) the Lorentz force is F = q[E + (v X B)]
Where E = -del phi - dA/dt
And B = del X A
(2) The potential energy equals U = qphi – qA dot v
How do I get from 1 to 2?
I’ve tried going from 1 to 2 and from 2 to 1 and I can’t figure it out. This isn’t a homework problem it comes form page 22 of Goldstein’s Mechanics.
Thanks
