Two metallic plates form a parallel plate capacitor. The distance between the plates is ' $\displaystyle d$ '. A metal sheet of thickness $\displaystyle \frac{d}{2}$ and of area equal to area of each plate is introduced between the plates. What will be the ratio of the new capacitance to the original capacitance of the capacitor?
