일반물리학 2 — Capacitance: Problem 39

39 In Fig. 25-35, the capacitances are \(C_1 = 1.0\text{ }\mu\text{F}\) and \(C_2 = 3.0\text{ }\mu\text{F}\), and both capacitors are charged to a potential difference of \(V = 200\text{ V}\) but with opposite polarity as shown. Switches \(S_1\) and \(S_2\) are now closed. (a) What is now the potential difference between points \(a\) and \(b\)? What now is the charge on capacitor (b) 1 and (c) 2?
