A parallel-plate capacitor with distance of separation between the plates, d, is fully charged and the terminals are disconnected from the battery. The plates are then pulled apart to increase their separation to 2d. Finally, a dielectric with K-4 is inserted between the plates. Which of the following statements is true? O The energy stored in the capacitor is half the original level. The energy stored in the capacitor is one quarter the original level. O The energy stored in the capacitor is not changed. O The energy stored in the capacitor is four times the original level. The energy stored in the capacitor is twice the original level.
