An isolated parallel-plate capacitor (not connected to a battery) has a charge of Q = 1.7×10−5C. 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 2.6 mm, if the charge on the plates remains constant. The capacitor plates are in a vacuum. Express your answer using two significant figures. (unit in J)
