Abstract
In this work we investigate an approximate solution to Kaluza-Klein's equations for a charged system with spherical symmetry. We find that the 4-dimensional metric does not approximate the Reissner-Nordstrøm metric in the limitr→∞. Moreover, we investigate the low-velocity motion of a test particle in the field of our charged object. We find that Kaluza-Klein's corrections to Lorentz's force could be sufficiently large to be measured. This experimental evidence could be used to support (or reject) the five-dimensional relativity in its present form.
