A capacitor with a 3 mm gap has a potential difference of 6 volts (see the figure). A disk of glass 1.64 mm thick, with area the same as the area of the metal plates, has a dielectric constant of 1.9. It is inserted in the middle of the gap between the metal plates. Now what is the potential difference of the two metal disks? (It helps to make a diagram showing the electric field along a path.)
