$.$ Two small surfaces, A and B$,$ are placed inside an isothermal enclosure at a uniform temperature. The enclosure provides an irradiation of $6300$ W$/$m$2$ to each of the surfaces and surfaces A and B absorb incident radiation at rates of $5600$ and $630$ W$/$m$2,$ respectively. Consider conditions after a long time has elapsed. what is the net heat fluxes

Answer the question from $5\mathrm{.}1$ to $5\mathrm{.}2.$
