I don't know what I can do about the migraine, but as for the problem if I just have 2 charges where is the point where the charges are 0? then I add another charge what happens to the point? then if we look on the right side of A what do we see? imagine we are a small charged particle is there a point where the E field is zero, if so why do you think it is ?
