Assuming the Sun to be a spherical body of radius R at temperature of T K, evaluate the total radiant power incident on the Earth, at a distance r from the Sun. Where r0 is the radius of the Earth and \(\odot\) the Stefan's constant.
- \(\frac{4 \pi r_{n}^{2} R^{2} \sigma T^{4}}{r^{2}}\)
- \(\frac{\pi r_{n}^{2} R^{2} \sigma T^{4}}{r^{2}}\)
- \(\frac{r_{n}^{2} R^{2} \sigma T^{4}}{4 \pi r^{2}}\)
- \(\frac{R^{2} \sigma T^{4}}{r^{2}}\)
Answer
(A) 4 r_ n ^ 2 R^ 2 T^ 4 r^ 2
