What is the flux on a solar sail per square meter, if it orbits the Sun at 3 AU. Flux at 1 AU is 1.36 KW/square meter
Flux goes as 1/r^2
The Attempt at a Solution
Flux at 3 AU will be 1.36/3^2 = 1.36/9 = 0.15 KW/square meter
I can't figure out how to relate this to the force though?
Any help would be appreciated.
