Two identical metallic sheets each behaves like a black body are kept parallel to each other with small separation between them in vacuum. Thermal energy is generated at a constant rate `P` in one of the sheets by a passing electricity in it. In steady state, temperature of the other sheet is found to be constant is `300K` . Find the value of `P` in Kilo-Watt. (Given area of the plates `A=(10^(3))/(17times27)m^(2)` and `sigma=(17)/(3)times10^(-8)W`/`m^(2)``K^(4)`
