A battery is used to charge a parallel-plate capacitor so that the magnitude of the potential difference between its plates is 16.0 V. The capacitor is disconnected from the battery (so the amount of charge on each plate cannot change), and a material with a dielectric constant of 3.49 is inserted between the plates. Find the new potential difference between the plates.
