Abstract

Lorentz proposed a classical model of electron in which it was assumed the electron to have only `electromagnetic mass'. We modelled electron as a charged anisotropic perfect fluid sphere admitting non-static conformal symmetry. We find that the pressure and density fail to be regular at the origin, but the effective gravitational mass is regular everywhere and vanishes in the limit r→0, i.e. it does not have the problem of singularity. Further, we have matched the interior metric with the exterior (Reissner-Nordström) metric and determine the values of the parameters k and r0 (occurring in the solutions) as functions of mass, charge and radius of the spherically-symmetric charged object, i.e. electron.
