Um Modelo Macroscópico para a Força de Reação Radiativa.

Abstract

We present a simple macroscopic system, a spherical shell with a uniform charge distribution, inside of which we put a test charge. We show that the spherical shell charge distribution, when accelerated, produces a non null electromagnetic field that acts on the test charge i nducing, near the spherical shell center, force such as the Lorentz-Dirac radiation reaction one.
