Physics - EMI/AC Question with Solution | TestHub

For ac circuit shown in figure, $\mathrm{R}=100\mathrm{k}\Omega$ and $\mathrm{C}=100\mathrm{pF}$ and the phase difference between ${\mathrm{V}}_{\text{in }}$ and $\left(V_B-V_A\right)$ is $90^{\circ }$. The input signal frequency is $10^x\mathrm{rad}/\sec$, where ' x ' is ______
