A parallel plate capacitor with air between the plate has a capacitance of $\displaystyle 15$ pF . The separation between the plate becomes twice and the space between them is filled with a medium of dielectric constant $\displaystyle 3.5$ . Then the capacitance becomes $\displaystyle \frac{x}{4} \mathrm{pF}$. The value of $\displaystyle x$ is $\displaystyle \_\_\_\_$.
