Five identical capacitor plates are arranged so that adjacent plates form capacitors of 2 µF each. The plates are connected to a 10 V source as shown. Find the charge on plate C.

Question

G1 Physics · Accepted Answer

Each gap acts as a 2 µF capacitor. Use the plate connections shown and Q = CV on the two surfaces adjacent to plate C; the algebra gives net charge +40 µC on C. Hence B.
