A certain substance has a dielectric constant of 3.06 and a dielectric strength of 15.0 MV/m. If it is used as the dielectric material in a parallel-plate capacitor, what minimum area should the plates of the capacitor have to obtain a capacitance of 6.10 x 10-2 µF and to ensure that the capacitor will be able to withstand a potential difference of 3.15 kV?
