The two metal objects in Fig. 25-25 have net charges of +70pC and-70pC, which result in a 20V potential difference between them. (a) What is the capacitance of the system? (b) If the charges arechanged to +200pC and -200pC, what does the capacitance become?
If the capacitance for part b is independent of q, why then is the formula q/ΔV
would the answer be different if it started as 200? how then is itindependent
