Two identified parallel plate capacitors
A and
B are connected to a battery of
V volts with the switch
S closed. The switch is now opened and the free space between the plates of the capacitors is filled with a dielectric of dielectric constant
K. Find the ratio of the total electrostatic energy stored in both capacitors before and after the introduction of the dielectric.
