Transcribed Image Text:A 2.0 cm diameter circular parallel plate
capacitor with a spacing of 0.5 mm is charged
to 200 V. Assume the mediums between the
two parallel plates is a vacuum.
i) The voltage source is removed and the
spacing increased to 1.0 mm. Does the energy
stored in the electric field change? If so, what
is its new value?
ii) With the voltage source disconnected, the
spacing is reduced back to 0.5 mm. The
capacitor is then filled with a material with a
dielectric constant of 5.0. What is the potential
difference after the dielectric is added?
