Hello everyone...I'm runnning int problems on this problem:
he two metal objects in Fig. 25-26 have net charges of +62 pC and -62 pC, which result in a 14 V potential difference between them.

(a) What is the capacitance of the system?
4.429 pF
(b) If the charges are changed to +226 pC and -226 pC, what does the capacitance become?
wrong check mark pF
(c) What does the potential difference become?
V
If the charges are the same, i thought that ment it would be in series, which is Q = CVtotal
So i put in:
C = 226pC/14V = 16.14 pF
I also tried 0, both wrong. ANy ideas? Thanks
