(24.28) A parallel-plate vacuum capacitor has 8.38 J of energy stored in it. The
separation between the plates is 2.30 mm. If the separation is decreased to 1.15
mm, what is the energy stored
a. if the capacitor is disconnected from the potential source (explain what
happens to the energy)
b. if the capacitor remains connected to the potential source (explain what
happens to the energy)
