If half of the space between the plates of a parallel plate capacitor is filled with a medium of dielectric constant 4, the capacitance is C 1 . If one-third of the space between the plates of the capacitor is filled with the same medium of dielectric constant 4, the capacitance is C 2 . If in both cases, the dielectric is placed parallel to the plates of the capacitor, then C 1 : C 2 =
