Problem
The potential across a 3 μF capacitor is 12 V when it is not connected to anything. It is then connected in parallel with an uncharged 6 μF capacitor. At equilibrium, the charge q on the 3 μF capacitor and the potential difference V across it are
(a) q=12 μC, V=4 V; (b) q=24 μC, V=8 V;
(c) q=36 μC, V=12 V; (d) q=12 μC, V=6 V.
