Two highly conducting shells A and B have radius R and 2 R and are concentric. Temperature of A is maintained at $2 T_{0}$ and the arrangement is kept in an encloser of temperature $T_{0}$ as shown. In steady state the temperature of B is :

Options:

Answer:

Solution:

For shell B to be in steady state Power absorbed = Power radiated B absorbs all radiations of $A = 16 \times 4 π R^{2} T_{0}^{4} σ$ B absorbs all radiations of surrounding $= 4 \times 4 π R^{2} σ T_{0}^{4}$
