A Parallel Plate Capacitor Has a Paper Dielectric Having Dielectric $8.0 \mathrm{kV} / \mathrm{mm}$

A parallel plate capacitor has a paper dielectric having dielectric strength $8.0 \mathrm{kV} / \mathrm{mm}$ and dielectric constant 3.0. The plate area is $3000 \mathrm{~cm}^{2}$ and the plate separation is $0.50 \mathrm{~mm}$ . What is the highest voltage that can be applied to this capacitor before breakdown occurs?

A) $4.0 \times 10^{3} \mathrm{~V}$
B) $1.2 \times 10^{4} \mathrm{~V}$
C) $15 \mathrm{~V}$
D) $4.0 \times 10^{2} \mathrm{~V}$
E) $1.2 \times 10^{2} \mathrm{~V}$
