An isolated air-filled parallel-plate capacitor that is no
longer connected to anything has been charged up to Q = 3.4 nC. The
separation between the plates initially is 3.4 mm, and for this
separation the capacitance is 63 pF. Calculate the work that must
be done to pull the plates apart until their separation becomes 6.7
mm, if the charge on the plates remains constant. (ε0 = 8.85 ×
10-12 C2/N ∙ m2). Give you answer to the nearest 0.01...

An isolated parallel-plate capacitor (not connected to a
battery) has a charge of Q = 4.8×10−5C. 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 9.1 mm, if the charge on the plates remains constant. The
capacitor plates are in a vacuum.
