Energy in Capacitors: An ideal, isolated, air-filled parallel-plate capacitor is not connected to a battery but has equal and opposite charges of 3.9 nC on its plates. The separation between the plates initially is 1.2 mm, and for this separation the capacitance is 3.1 × 10-11 F. How much work must be done to pull the plates apart until their separation becomes 7.7 mm? (?0 = 8.85 × 10-12 C2/N ? m2)
