A telegraph line of length $\displaystyle 100$ km has a capacity of $\displaystyle 0.01 \mu \mathrm{~F} / \mathrm{km}$ and it carries an alternating current at $\displaystyle 0.5$ kilo cycle per second. If minimum impedance is required, then the value of the inductance that needs to be introduced in series is
\_\_\_\_ mH . (if $\displaystyle \pi=\sqrt{10}$ )
Official answer
100
