In the steady state, no current is flowing through the capacitor branch, so the capacitor branches may be removed from the circuit, the equivalent circuit is shown in figure. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/db32b48c1e0812cd33f50cc1e1b3ee53-.png" /> ∴ RA B=R1+R2=r+r=2 r

Q. The equivalent resistance between points $A$ and $B$ in figure at steady state will be

$2 r$

$\frac{3}{5} r$

$\frac{5}{3} r$

none of these

In the steady state, no current is flowing through the capacitor branch, so the capacitor branches may be removed from the circuit, the equivalent circuit is shown in figure.

$∴ R_{A B} = R_{1} + R_{2} = r + r = 2 r$
