The network shown is assembled with uncharged capacitors X , Y, and Z, with
CX=3.0 F, CY=5.0 F and CZ=1.0 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. How much charge is finally stored in capacitor Y?
