A black body radiates heat energy at the rate of

2 \times 10^5 \mathrm{~J} / \mathrm{sm}^2

at temp. of

127^{\circ} \mathrm{C}

. The temp of black body at which rate becomes

32 \times 10^5 \mathrm{~J} / \mathrm{s}-\mathrm{m}^2

is:

View answer and explanation

Correct option: B

527^{\circ} \mathrm{C}

Option B (

527^{\circ} \mathrm{C}

) is correct because it is the temperature at which the black body radiates heat at the specified rate, calculated using Stefan-Boltzmann law.
