Is it me, or the overall problem in CED is not addressed anywhere? Statement of the problem: Let there be two massive electrically charged particles of invariant masses m1 and m2 and electric charges q1 and q2, respectively. They are free to move arbitrarily in Minkowski spacetime endowed with (+---) metric tensor. One is further given the full vacuum set of Maxwell's equations written in terms of a generic electric field E and magnetic field B. Please, write down (in covariant form, i.e. using spacetime (pseudo)tensors) the full set of dynamical equations for the motion of particles and the 2 fields that they generate. How are all these equations written in the presence of a gravitational field described by GR? What do you think? Is the problem written somewhere, together with the solution, or can we (you) write the down the solution here? EDIT after 3 days: NO TAKE? Ok, I will spend more time reading/working on this.
