Hey y'all. I'm not sure how I'm supposed to resolve the questions about the following circuit:  The questions are as follow:
What is the voltage between points A and B when the switch is open?
What is the voltage between points A and B when the switch is closed?
What is the ΔQ is each capacitor from when the switch is open until a lot of time after the switch has closed?

Any help is appreciated!
Thanks in advance for all the responses!

Since this is homework, you need to show your work so we can see where you're having difficulty.

Take them one at a time and make your best effort. In particular, try to explain what your reasoning and approach is and what assumptions you are making.
