Homework Answers
a) capacitance = Aeo / d
= 0.06*0.06*8.85*10^-12 / 10^-3
= 31.86*10^-12 F = 31.86 pF
Q = CV = 31.86*9 = 286.74 pC
D) Charge remains same
Capacitance become half . since separation becomes double
C = 31.86 / 2 = 15.93 pF
V = Q/C = 286.74 / 15.93 = 18V

Two circular metal plates with radii of 10.0 cm are separated by a distance of 0.200 mm. They are connected to the terminals of a car battery (treat as 12.0 V). (d) You now return the plates to their original separation and allow a long time to go by so that the capacitor is fully charged. You then disconnect the battery from them. Again, using insulated plates, you pull the plates apart until they are separated by 0.400 mm. Now...
