A First Course in String Theory
The Lorentz force equation (3.5) can be written relativistically as
where is the four-momentum.
(a) Check explicitly that this equation reproduces (3.5) when is a spatial index.
(b) What does (1) gives when ? Does it make sense?
The spacetime interval is Lorentz invariant. If , we have Eq. (2.27) and (2.28):
