6.0\,\mu\text{F}

capacitor is charged to a potential difference of

200\,\text{V}

and then disconnected from the battery. A dielectric material with dielectric constant

\kappa = 3.0

is later inserted completely between the plates. Determine the energy stored in the capacitor after the dielectric is inserted.
