Voltage rating of a parallel plate capacitor is $\displaystyle 500$ V . Its dielectric can withstand a maximum electric field of $\displaystyle 10^6 \mathrm{~V} / \mathrm{m}$. The plate area is $\displaystyle 10^{-4} \mathrm{~m}^2$. What is the dielectric constant if the capacitance is $\displaystyle 15$ pF ? (given $\displaystyle \epsilon_0=8.86 \times 10^{-12} \mathrm{C}^2 / \mathrm{Nm}^2$ )
