Two Carnot engines A and B are operated in series. The first one, A receives heat at \[{{T}_{1}}(=600K)\]and rejects to a reservoir at temperature\[{{T}_{2}}\]. The second engine B receives heat rejected by the first engine and in turn, rejects to a heat reservoir at\[{{T}_{3}}(=400K)\]. Calculate the temperature \[{{T}_{2}}\] in kelvin if the work outputs of the two engines are equal:
