Question - 2
Two conducting cylinders are connected in series with each other. They are kept between two heat baths at temperatures T1 = 200 K and T2 = 400 K as shown in the figure. Radius of the smaller cylinder is half the radius of bigger one, whereas, both of them have same length L. Thermal conductivities of the materials of the larger and the smaller cylinders are K1 and K2 respectively. In steady state, if temperature at the junction of the two cylinders is 300 K. then \(\left(\frac{\mathrm{K}_{1}}{\mathrm{~K}_{2}}\right)\) will be ________.
- A 0.13
- B 0.25
- C 0.15
- D 0.45
