What is the temperature of the steel -copper junction in the steady state of the system shown in the figure. Length of the steel rod `=25cm`, length of the copper rod `=50cm`, temperature of the furance `=300^(@)C`, temperature of the other end `=0^(@)C`. The area of cross section of the steel rod is twice that of the copper rod. (Thermal conductivity of steel `=50Js^(-1)m^(-1)K^(-1)` and of copper `=400 J s^(-1)m^(-1)K^(-1)`)
