The parallel plates in a capacitor, with a plate area of 5.80 cm2 and an air-filled separation of 4.90 mm, are charged by a 8.10 V battery. They are then disconnected from the battery and pulled apart (without discharge) to a separation of 6.70 mm. Neglecting fringing, find (a) the potential difference (in V) between the plates, (b) the initial stored energy, (c) the final stored energy, and (d) the work required to separate the plates.

Two parallel plates, each having area A = 2797cm2 areconnected to the terminals of a battery of voltage Vb = 6 V asshown. The plates are separated by a distance d = 0.53cm. You mayassume (contrary to the drawing) that the separation between theplates is small compared to a linear dimension of the plate.
