The distance between two plates of a capacitor is d and its capacitance is $\displaystyle \mathrm{C}_1$, when air is the medium between the plates. If a metal sheet of thickness $\displaystyle \frac{2 d}{3}$ and of the same area as plate is introduced between the plates, the capacitance of the capacitor becomes $\displaystyle \mathrm{C}_2$. The ratio $\displaystyle \frac{\mathrm{C}_2}{\mathrm{C}_1}$ is
