Consider a wire with charges moving with speed 'v'and '-v' in frame F (with charge q at distance s away moving at speed u).
In frame F', the charge q is stationary, and so the speeds of the charges in the wire are v+ and v-, where v- > v+
Hi guys, I have trouble following through the proof in step 12.81 and 12.82:
How did they get rid of the ± in the denominator? I tried using a2 - b2 = (a+b)(a-b) but it doesn't match the expression:
