Three very large plates of same area are kept parallel and close to each other. They are considered as ideal black surface and have very high thermal conductivity The first and thired plates are maintained at temperatures `2T` and `3T` respectively Find the temperature of the middle (i.e second) plate under steady state .

Three very large plates of same area are kept parrallel and close to each other. They are considered as ideal black surfaces and have high thermal conductivity. The first and third plates are maintained at temperatures 2T and 3T respectively. The temperature of the middle (i.e., second) plate under steady state condition is

Three very large plates of same area are kept parallel and close to each other. They are considered as ideal black surfaces and have very high thermal conductivity. First and third plates are maintained at absolute temperatures 2T and 3T respectively. Temperature of the middle plate in steady state is

Three large identical plates are kept close and parallel to each other. The outer two plates are maintained at temperatures T and 2T. respectively. The temperature of the middle plate in steady state will be close to

Three large discs have same area. They are kept at equidistant in parallel. They can be considered as perfect black bodies and their thermal conductivity is very large. If temperature of first and third discs are 2T C and 3T C respectively then temperature of second disc in thermal steady state is . . . . .
