Answer:
Force of 17.6 micrometer is acting on the surface due to the sunlight.
Explanation:
Given that,
Intensity of sunlight is [tex]I=637\ W/m^2[/tex]
It strikes a flat collecting surface perpendicularly and is totally absorbed. The area of the surface is [tex]A=8.33\ m^2[/tex]
[tex]P=F\times v[/tex]
So, force is given by :
[tex]F=\dfrac{IA}{c}[/tex]
c is speed of light
[tex]F=\dfrac{637\times 8.33}{3\times 10^8}\\\\F=17.6\ \mu N[/tex]
So, force of 17.6 micrometer is acting on the surface due to the sunlight.
