A parallel-plate capacitor with plate area

0.020\,\text{m}^2

and plate separation

0.80\,\text{mm}

is initially vacuum-filled and carries

+2.5\,\mu\text{C}

of charge on one plate. After the battery is disconnected, a dielectric slab of constant

\kappa = 5.6

completely fills the gap. Determine the new potential difference between the plates (in volts).
