$\displaystyle \mathrm{C}_{\mathrm{o}}$ is the capacitance of a parallel plate capacitor with air as a medium between the plates (as shown in Fig. $\displaystyle 1$). If half space between the plates is filled with a dielectric of relative permittivity $\displaystyle \varepsilon_{\mathrm{r}}$ (as shown in Fig. $\displaystyle 2$), the new capacitance of the capacitor will be :
Official answer
(1)
$\displaystyle \frac{\mathrm{C}_{\mathrm{o}}}{2}\left(1+\varepsilon_{\mathrm{r}}\right)$
