The solar energy received by the Earth persquare metre per minute is `8.315 xx 10^(4)Jm^(-2)min^(-1)`. If the radius of the Sun is` 7.5 xx 10^(5)` km and the distance of the Earth from the Sun is `1.5 xx10^(8)` km, calculate the surface temperature of Sun. Assume the Sun as a perfect black body. Given that Stefen constanta ` sigma = 5.7 xx 10^(-8)Wm^(-2)K^(-4).`
