The capacitors in the figure View Figure are initially uncharged and are connected, as in the diagram, with switch S open. The applied potential difference is V_{ab}= + 210 {V}.
What is the potential difference V_{cd}?
70 V
Correct

Part B
What is the potential difference V_{ad}...
Ok well I got the voltages across each capacitor, but I am now stuck on how much charge flows through that switch. Shouldn't it be 210*Capacitance equivalent?
I got for 210*Ceq as 1.89*10^-3 but its wrong.
Any hints?
woops sorry, it asks first for the voltage between c and d when the switch is open, which I got. 70V. Then it goes to ask the potential across each capacitor when the switch is closed, which is the part I am confused about. Lastly it asks the total charge through the switch.
Thanks and sorry...
Homework Statement
Well the only thing the problem gives is 210 V
