Value of $R$ in the oscillator circuit shown in the given figure, so chosen that it just oscillates at an angular frequency of $\omega$. The value of $\omega$ and the required value of $R$ will respectively be

1. $10^{5} \mathrm{rad} / \mathrm{sec}, 2 \times 10^{4} \Omega$ -
2. $2 \times 10^{4} \mathrm{rad} / \mathrm{sec}, 2 \times 10^{4} \Omega$
3. $2 \times 10^{4} \mathrm{rad} / \mathrm{sec}, 10^{5} \Omega$
4. $10^{5} \mathrm{rad} / \mathrm{sec}, 10^{5} \Omega$
