Consider a parallel plate capacitor. When half of the space between the plates is filled with some dielectric material of dielectric constant $K$ as shown in Fig. (1) below, the capacitance is $C_1$ . However, if the same dielectric material fills half the space as shown in Fig. (2), the capacitance is $C_2$ . Therefore, the ratio $C_1: C_2$ is

Question

Consider a parallel plate capacitor. When half of the space between the plates is filled with some dielectric material of dielectric constant

K

as shown in Fig. (1) below, the capacitance is
