  Within the framework of General Relativity a model approach to a description
of spherical gravitating static fluid balls with an electric charge is
considered. The metric interval is written in Bondi's radiation coordinates.
The total energy-momentum tensor as a direct sum of the perfect Pascal fluid
energy-momentum tensor and the energy-momentum tensor of an electromagnetic
field is chosen. The exact solution of the Einstein-Maxwell equations as an
extension of similar solution with parabolic distribution of mass density is
found.
