A heat source at \( \mathrm{T}=10^{3} \mathrm{~K} \) is connected to another heat reservoir at \( \mathrm{T}=10^{2} \mathrm{~K} \) by a copper slab which is
P
\( 1 \mathrm{~m} \) thick. Given that the thermal conductivity of
W
copper is \( 0.1 \mathrm{WK}^{-1} \mathrm{~m}^{-1} \), the energy flux through it in the steady state is:
(1) \( 90 \mathrm{Wm}^{-2} \)
(2) \( 120 \mathrm{Wm}^{-2} \)
(3) \( 65 \mathrm{Wm}^{-2} \)
(4) \( 200 \mathrm{Wm}^{-2} \)
