Physics Question from JEE Main 2025 · 7 April, Shift 1

For the AC circuit shown in the figure, R=100kΩR = 100 \, k\Omega and C=100pFC = 100 \, pF, and the phase difference between VinV_{in} and (VBVA)(V_B - V_A) is 9090^\circ. The input signal frequency is 10x10^x rad/sec, where xx is:

AC source connected across two vertical RC branches; left branch has resistor on top and capacitor below with node A between them, right branch has capacitor on top and resistor below with node B between them.
