Two square conducting plates of length L are separated by a distance D. If a dielectric block of constant k is inserted to a distance x between the plates, as shown in the figure, and we assume that the capacitor is connected to a battery that maintains a constant potential difference V between the plates, the equivalent capacitance of the system is: a. Cequi = (ϵoL/D) [L+x(k−1)] b. Cequi = (ϵoL/D) [L+x(2k−1)] c. Cequi = (ϵoL/D) [L+x(k−2)] d. None of the above

Two conducting shapes are charged with +1µC and -1µC. There is a region between them (shown in grey in the figure) where their surfaces are flat and parallel and separated by 10-4m.
