1. [8 pts] Parts (a) and (b) of this question refer to the following linear configuration of charges (A-D). All charges have the same absolute value and are equidistant from their nearest neighbors (including the black dot). A. B. C. D. + a) Rank the charge configurations based on the magnitude of the net electric field at the black dot, from greatest to least. You must explain your reasoning for full credit. b) Rank the charge configurations based on the value of the electric potential at the black dot, from most positive to most negative. You must explain your reasoning for full credit
