In the gure the capacitances are C1 = 0.80 HF and C2 = 3.2 pF, and both capacitors are charged to a potential difference of V = 80V but with opposite polarity as shown. Switches 51 and 52 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
