The drawing shows three point charges arranged in three
Chapter 18, Problem 18.168(choose chapter or problem)
The drawing shows three point charges arranged in three different ways. The charges are q, q, and q; each has the same magnitude, with one positive and the other two negative. In each of the arrangements the distance d is the same. Rank the arrangements in descending order (largest first) according to the magnitude of the net electrostatic force that acts on the positive charge.
