In a parallel plate capacitor the separation between plates is 3.y. This separation is filled by two layers of dielectrics, in which one layer has thickness and dielectric constant 3 K. the other layer is of thickness 2x and dielectric constant 5 K. If the plates of the capacitor are connected to a battery, then the ratio of potential difference across the dielectric layers is
