Capacitors in Combination: The network shown is assembled with uncharged capacitors X , Y, and Z, with CX = 4.0 ?F, CY = 6.0 ?F, and CZ = 5.0 ?F. The switches S1 and S2 are initially open, and a potential difference Vab = 120 V is applied between points a and b. After the network is assembled, switch S1 is then closed, but switch S2 is kept open. What is the final potential difference across capacitor X?
A. 120 V
B. 82 V
C. 75 V
D. 67 V
E. 60 V
