Question

Two conducting cylinders of equal length but different radii are connected in series between
two heat baths kept at temperatures T₁= 300 K and T₂ = 100 K, as shown in the figure. The
radius of the bigger cylinder is twice that of the smaller one and the thermal conductivities of the
materials of the smaller and the larger cylinders are K₁ and K₂ respectively. If the temperature at
the junction of the two cylinders in the steady state is 200 K, then K₁ / K₂ =__________.
