Two metal objects, a saw and a wrench, are lying side-by-side on an non-conducting table; the two metal objects are not in contact with one another; they have net charges of +85.0 pC and -85.0 pC, and this results in a 15 Volt potential difference between them.
(a) Obtain the capacitance of this system?
F
(b) If the charges are changed to +215.0 pC and -215.0 pC, find what does the capacitance become?
F
(c) Determine what does the potential difference become?
V
