Parallel rays of light of intensity I=912Wm−2 are incident on a spherical black body kept in surroundings of temperature 300 K. Take Stefan-Boltzmann constant σ=5.7×10−8Wm−2K−4 and assume that the energy exchange with the surroundings is only through radiation. The final steady state temperature of the black body is close to
