Question

Select One Option Correct from the following :Three rods of identical cross-sectional area and made from the same metal form the sides of an isosceles triangle ABC, right√angled at B. The points A and B are maintained at temperatures T and$\sqrt{2}T$ , respectively. In the steady state, the temperature of the point C is $T_c$. Assuming that only heat conduction takes place, $T_c/T$ is
(A) $\frac{1}{2(\sqrt{2} -1)}$
(B) $\frac{3}{\sqrt{2} +1}$
(C) $\frac{1}{\sqrt{3}(\sqrt{2} -1) }$
(D) $\frac{1}{\sqrt{2} +1}$
