Question

In a solar system far far away, the sun's intensity is 400 W/m2 for a planet located a distance R away. What is the sun's intensity for a planet located at a distance 6 R from the Sun? W/m2
In a not so far away solar system, the sun's intensity is 20 W/m2 for a planet located a distance R away. What is the sun's intensity for a planet located at a distance R/2 from the Sun? W/m^2 In a solar system far far away, the sun's intensity is 400 W/m2 for a planet located a distance R away. What is the sun's intensity for a planet located at a distance 6 R from the Sun? W/m2

In a not so far away solar system, the sun's intensity is 20 W/m2 for a planet located a distance R away. What is the sun's intensity for a planet located at a distance R/2 from the Sun? W/m^2

Explanation / Answer

Intensity is inversely proportional to square of distance

I2/I1 = r1^2/r2^2

I1 = 400 W/m^2

I2 =?

r1= R

r2 = 6R

I2/400 = 1/36

I2 = 11.11 W/m^2    <<<----answer

--------------------------

I2/I1 = r1^2/r2^2

I1 = 20 W/m^2

I2 =?

r1= R

r2 = R/2 = 0.5*R

I2/20 = 1/0.5^2

I2 = 80 W/m^2    <<<----answer
