Abstract:
The formulation of the equivalence principle underlying the general theory of relativity is considered. Implications of the equivalence principle are discussed with regard to a charge placed in a locally uniform gravitational field or a uniformly accelerated reference frame (the problem was addressed earlier elsewhere, for example by Ginzburg and co-workers in 1962). The criticism by Logunov and co-workers of the canonical equivalence principle in electrodynamics as presented in the earlier review by Ginzburg and co-workers is shown to be irrelevant.
