A capacitor has a capacitance of 49 micro-farads without a dielectric while connected to a 20 volt battery. Then the distance between the plates is decreased by a factor of 5 and a dielectric with a dielectric constant of 2.29 is inserted between the plates of the capacitor while still connected to the same battery. What is voltage, in volts, across the capacitor after the dielectric and the distance between the plates have been changed?
