3. Consider a solution containing dipolar molecules each having a positively charged head and a negatively charged tail. In the absence of an electric field the molecules point north (n), south (s), east (e), and west (w) with equal probabilities (distribution shown in Fig. 3a). A different probability distribution (shown in Fig. 3b), however, is found when a field is applied to the solution.
