The Plates of a Parallel Plate Capacitor Each Have an Area

The plates of a parallel plate capacitor each have an area of 0.40 m² and are separated by a distance of 0.02 m. They are charged until the potential difference between the plates is 3000 V. The charged capacitor is then isolated.
-Determine the magnitude of the charge on either capacitor plate.

C) 4.9 × 10^-7 C
D) 5.4 × 10^-7 C
E) 6.8 × 10^-7 C
