$$3.8\times 10^{-8}\ H$$

Explanation:

Given the $$6.7\mu F$$ capacitor is used in an LC circuit to produce $$10\ kHz$$ frequency.

We need to find the value of inductance required.

As we know the relation between angular frequency in $$rad/sec$$ and frequency in $$Hz$$ is.

$$\omega =2\times \pi\times f$$

Where $$\omega$$ is angular frequency and $$f$$ is frequency.

$$\omega=2\times \pi\times 10\times 1000=20000\pi\ rad/sec\\\omega=62832\ rad/sec$$

Also, the relation between the angular frequency, capacitance and inductance is given by.

$$\omega^2=\frac{1}{LC}\\\\L=\frac{1}{\omega^2C} \\\\L=\frac{1}{62832^2\times6.7\times 10^{-6} } \\\\L=\frac{1}{26451}.\\ \\L=3.8\times 10^{-8}\ H$$

So, $$3.8\times 10^{-8}\ H$$ inductance will be required to produce $$10\ kHz$$.
