Escape of photons from charged bodies

Abstract

We show here that the restriction of photons issuing from the surface of an uncharged sphere with Schwarzschild radius to the radial direction is removed for a charged sphere. Also we establish that in the case of a charged infinitely long cylinder the mass per unit length does not impose any restriction on the photons issuing from the surface in non-radial directions unlike in the case of uncharged infinitely long cylinders. But in the limit when the radius of the charged cylinder approaches a certain value depending on the mass per unit length and the charge per unit length, only the radially moving photons may escape.
