  By using the higher-order geodesic deviation equations for charged particles,
we apply the method described by Kerner et.al. to calculate the perihelion
advance and trajectory of charged test particles in the Riessner-Nordstrom
spacetime. The effect of charge on the perihelion advance is studied and
compared the results with those obtained earlier via the perturbation method.
The advantage of this approximation method is to provide a way to calculate the
perihelion advance and orbit of planets in the vicinity of massive and compact
objects without considering Newtonian and post-Newtonian approximation.
