Parallel rays of light of intensity I = 912 Wm2 are incident on a spherical black body kept in surroundings of temperature 300 K. Take Stefan-Boltzmann constant o = 5.710 Wm K 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 (A) 330 K (B) 660 K (C) 990 K (D) 1550 K Parallel rays of light of intensity I = 912 Wm2 are incident on a spherical black body kept in surroundings of temperature 300 K.
