Orbital And Mass Defect Effects In The Gravitational Field

In this paper, from the equations of motion, we obtain the orbital and mass defect effects in the gravitational field. In the first section, we review the tested experiments about the General Relativity and the newdeductions of modern gravitational theory----effects ofthe gravitation. We elaborate the studied gravitational fields and their properties. In the second section, from the geodesic equation, we deduce the orbital differential equation of the test particle, then using the method of undetermined coefficient, we yield the expression of the perihelion precession in the gravitational field, and substituting the metric of the Reissner-Nordstrom-Kasuya (R-N-K) spacetime into the orbital differential equation, we obtain the orbital effect of the test particle in the R-N-K field. Then, discussing the parameters in the expression of the orbital effect, we derive the orbital effects of the test particle, under different conditions and in different fields. In the third section, first, we elaborate the mass defect effects of the test particle, the...
