(20) An isolated parallel-plate capacitor (not connected
to a battery) has a charge of Q=1.410-5 C. The
separation between the plates initially is d=1.2 mm, and
for this separation the capacitance is 3.1x10-11 F.
Calculate the work that must be done to pull the plates apart until
their separation becomes 4.5 mm, if the charge on the
plates remains constant. The capacitor plates are in a vacuum.
Show your work!!!
Also plz include a picture/description of the problem too
plz.

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.
