Figure 24-22 shows three sets of cross sections of equipotential surfaces; all three cover the same +5q p -5q size region of space. (a) Rank the -q -2q +4q arrangements according to the Fig. 24-21 Question l. magnitude of the electric field present in the region, greatest first. (b) In which is the electric field directed down the page?
