can someone help me with a,b,c,d, and e

(6%) Problem 10: Three capacitors are connected in series as shown in the gure. The capacitances are C1 = 8.7 pF, and C2 = 7.6 pF, C3 is unknown, and the charge stored in each capacitor is Q = 6.5 pC. I lIlcupcrlluxom A 20% Part (3) Express the capacitance Cof a capacitor in terms of charge Qand voltage AVon it. A 20% Part (b) Apply the above formula to capacitor C1 to find an expression for the potential difference AV\" across it. A 20% Part (c) Express the potential difference AV1 2 through potentials V1 and V2 where V1 and V2 are the potentials measured in the wires 1 and 2, respectively, relative to the negative side of the battery. A 20% Part (d) Calculate Vzin V given V1 = 9 V. A 20% Part (e) Repeat the above procedure for capacitor C2 and calculate the potential at point 3, V3 in V.
