The network shown is assembled with uncharged capacitors

X , Y

, and

Z

, with

C _ { X } = 3.0 \mu F

C _ { Y } = 5.0 \mu \mathrm { F }

and

\mathrm { C } _ { Z } = 1.0 \mu \mathrm { F }

. The switches

\mathrm { S } _ { 1 }

and

\mathrm { S } _ { 2 }

are initially open, and a potential difference

V _ { a b } = 120 \mathrm {~V}

is applied between points

a

and

b

. After the network is assembled, switch

\mathrm { S } _ { 1 }

is then closed, but switch

S _ { 2 }

is kept open. What is the final potential difference across capacitor

Z

?
