The earth receives its surface radiation...

The earth receives its surface radiation from the sun at the rate of 1400 `W//m^(2)`. The distance of the centre of the sun from the surface of the earth is `1.5 xx 10^(11)` m and the radius of the sun is `7.0 xx 10^(8)` m. Treating sun as a black body, it follows from the above data that its surface temeperature is

A

5801 K

B

`10^(6) K`

C
