Two capacitors are identical, except that one is empty and the other is filled with a dielectric ( = 4.30). The empty capacitor is connected to a 21.0 V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric such that it stores the same amount of electrical energy as the empty capacitor?(adsbygoogle = window.adsbygoogle || []).push({});

so here's my problem..... i don't have the distance across the plates or the plate area??? would i just start going into the equations and seeing if i can cancel things out???

any help would be appreciated
