An isolated parallel-plate capacitor (not connected to a battery) has a charge of Q = 1.2×10−5 .The separation between the plates initially is d = 1.2 mm, and for this separation the capacitance is 3.1×10−11F. Calculate the work that must be done to pull the plates apart until their separation becomes 6.9 mm, if the charge on the plates remains constant. The capacitor plates are in a vacuum.

A parallel plate capacitor has a charge Q, plates of area A and separation d, where , so that we can disregard the fringe field. Show that the magnitude of the force exerted on each plate by the other is F = Q2/(2e0A).You may use (with care!) the expression F = QE, or consider the change in potential energy of the capacitor as you change the separation of the plates. Or you may do both.
