The potential across a \( 3 \mu \mathrm{F} \) capacitor is \( 12 \mathrm{~V} \) when it is not connected to anything. It is then connected in parallel with an uncharged \( 6 \mu \mathrm{F} \) capacitor. At equilibrium, the charge \( q \) on the \( 3 \mu \mathrm{F} \) capacitor and the potential difference \( V \) across it are
(a) \( q=12 \mu C, V=4 \mathrm{~V} \)
(b) \( q=24 \mu \mathrm{C}, V=8 \mathrm{~V} \)
(c) \( q=36 \mu C, V=12 \mathrm{~V} \)
(d) \( q=12 \mu \mathrm{C}, V=6 \mathrm{~V} \)
