An inductor of inductance $\displaystyle 2 \mu \mathrm{H}$ is connected in series with a resistance, a variable capacitor and an AC source of frequency $\displaystyle 7$ kHz. The value of capacitance for which maximum current is drawn into the circuit is $\displaystyle \frac{1}{x} \mathrm{~F}$, where the value of $\displaystyle x$ is $\displaystyle \_\_\_\_$. (Take $\displaystyle \pi=\frac{22}{7}$ )
