When a parallel plate capacitor with air between the plates is connected to a battery, the plates acquire a charge of$2\mathrm{.}0$ uC$.$ While still connected to the battery, a dielectric with constant k $=2$ is inserted so as to completely fill theregion between the plates. The charge on the capacitor is now:A$)1\mathrm{.}0$ MCB$)2\mathrm{.}0$ uCC$)4\mathrm{.}0$ MCD$)0\mathrm{.}0$ C
