this is in reply to the answer I was given for chapter 4 problem 137. Thank you so much for the very complete answer that you sent down and I just have one remaining question why are they position vectors inverted. I mean if point P is the origin and then say you direct that position vector down to see where it touches the line of force of C then is the position vector inverted as if it's coming from...
