Yes, I did. Sorry, late night posting. Thank you for your reply.

Ok,I think I worked it out. The observer in the laboratory rest frame sees the electron beam moving and as such witnesses Lorentz contraction of the distance between the electrons. This means a relativistic correction to the charge density per unit length. This increases the repulsive force...

I wasn't sure whether to post this in the classical or relativity section. While pondering something I found an embarrassing gap in my knowledge. I can't quite get my head around this problem and I need a fresh perspective. Consider two beams of electrons moving parallel to each other. The...
