Homework 25.1
The two metal objects in Fig. 25-24 have net charges of +70 pC and -70 pC, which results in a 20 V
potential difference between them. (a) What is the capacitance of the system? (b) If
the charges are changed to +200 pC and -200 pC, what does the capacitance become?
(c) What does the potential difference become?
