A parallel plate capacitor is charged by a battery. Once it is charged, battery is removed. Now a dielectric material is inserted between the plates of the capacitor. Which of the following does not change?

When a dielectric is inserted into a charged parallel plate capacitor after disconnecting the battery, the charge on the plates remains unchanged because there is no external circuit for charge flow. However, the electric field, potential difference, and stored energy change. So, the correct answer is (c) Charge on the plates.
