Only if you assume no acceleration on the objects. But he said charge, so they do accelerate.

You'd have to figure out the position and velocity of each one relative to the others to figure would what the effect of the charge will be. And don't forget to include the propagation delay of the charge field.

This is by far not a simple problem. Much much harder than the N-body problem.

If the top poster had only left out "Physicists are ridiculous." it would have been quite an insightful post, instead it was an inciteful one.

Look up http://en.wikipedia.org/wiki/Einstein_field_equations - add in http://en.wikipedia.org/wiki/Stress-energy_tensor and you'll see that the motion of relativistic bodies is barely understood.

I'm upmoding him, because I think -7 is more than enough.
