SUMMARY
The discussion centers on the analysis of two capacitors, with capacitances of 30 μF and 60 μF, each initially charged to 50 μC and 70 μC, respectively, when connected in series. It is established that in a series configuration, the charge on each capacitor must be the same, leading to the conclusion that the initial charges are irrelevant once connected. The final potential differences across the capacitors are calculated to be 5/3 V and 7/6 V, indicating that none of the provided multiple-choice answers are correct.
