Problem

A parallel-plate capacitor has plate area

0.020\,\text{m}^2

and plate separation

1.0\,\text{mm}

. The space between the plates is completely filled with a material of dielectric constant

\kappa=3.0

. The capacitor is connected to a

12\,\text{V}

battery. What is the magnitude of the charge stored on either plate? a)

6.4\,\mu\text{C}

2.1\,\text{nC}

6.4\,\text{nC}

0.71\,\text{nC}
