The distance between two plates of a capacitor is \(d\) and its capacitance is \(C_1\), when air is the medium between the plates. If a metal sheet of thickness \(\frac{2 d}{3}\) and of same area as plate is introduced between the plates, the capacitance of the capacitor becomes \(C_2\). The ratio \(\frac{C_2}{C_1}\) is:
