... anywhere between the charges, a positive test charge would feel a force towards the + xaxis. To the right of the -20 C at x=+2 m, a positive test charge would be pulled to the left. Thus, only to the left of the origin, x<0, can a positive (or negative) test charge feel no force. Ftotal = 0 = k C2 ( ...

... For reasons having to do with relativity, for non-interacting, unit charge, spin- 1/2 particles one can show that g = 2. Of course, any unit charge particle will have interactions...we can keep track of how these interactions modify the magnetic moment of the particle. This is called quantum field t ...
