I am new to General Relativity, so this question might sound silly. I know that the source of gravitational field is the stress-energy tensor. What I wonder is how do I find the spacetime metric, gmn caused by a stationary charged particle? What is the stress-energy tensor of a stationary charged particle? Is it just the T00 component exist? Besides that, consider two particles in which the gravitational field caused by each particle will affect each other, how do I analyzed the motion of these two particles?
