Two metal cubes A and B of same size are arranged as shown in fig. The extreme ends of the combination are maintained at \[100{}^\circ C\]and \[0{}^\circ C\]as shown. The arrangement is thermally insulated. The coefficients of thermal conductivities of A and B are 300 W/m-\[{}^\circ C\]and 200 W/m-\[{}^\circ C\] respectively. After steady state is reached, the temperature of the interface will be(in \[{}^\circ C\])

Answer:

60.00
