Homework Help: Need help with the order of electric potential

  1. Sep 14, 2013 #1
    1. The problem statement, all variables and given/known data

    In the diagram below, there are two charges of ##+q## and ##−q## and six points (a through f) at various distances from the two charges.(See attachment) You will be asked to rank changes in the electric potential along paths between pairs of points.

    2. Relevant equations

    ##V = \dfrac{kQ}{r}## [Not sure if this is the correct form to use]

    3. The attempt at a solution

    I know the order of the point charges is

    ##B > A > C = D > F > E##

    I believe the order of change of potential should be...

    1. From c to b
    2. From d to a
    3. From c to d
    4. From b to a and from f to e
    5. From c to e

    Your post does not have an attachment.

    That is the potential of a single charge, but you have two charges.
