The capacitance of a parallel plate capacitor with air as medium is $\displaystyle 6 \mu \mathrm{~F}$. With the introduction of a dielectric medium, the capacitance becomes $\displaystyle 30 \mu \mathrm{~F}$. The permittivity of the medium is : $$\left(\epsilon_0=8.85 \times 10^{-12} \mathrm{C}^2 \mathrm{~N}^{-1} \mathrm{~m}^{-2}\right) $$
