Question

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T₁ and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T₂. For what value of T the efficiencies of the two engines are equal?(a) $\frac{T_{1}+T_{2}}{2}$(b) $\frac{T_{1}-T_{2}}{2}$(c) T₁T₂(d) $\sqrt{T_{1}T_{2}}$
