17. (a) After the switches are closed, the potential differences across the capacitors are the same and the two capacitors are in parallel. The potential difference from ato bis given by Vab= Q/Ceq, where Qis the net charge on the combination and Ceqis the equivalent capacitance. The equivalent capacitance is Ceq= C1+ C2= 4.0 ×10–6F. The total charge on the combination is the net charge on either pair of connected plates. The charge on capacitor 1 is ()()64111.010F100V1.010CqCV−−==×=×and the charge on capacitor 2 is
