Problem

An isolated parallel-plate capacitor has a capacitance of

5.0\,\mu\text{F}

and an initial potential difference of

12\,\text{V}

. After it is disconnected from any power source, a dielectric with constant

\kappa=3.0

is completely inserted between the plates. Determine the work that an external agent must do to insert the dielectric.
