Sunlight, with an intensity of 667 w / m², strikes a flat collecting surface perpendicularly and is totally absorbed. the area of the surface is 9.03 m². what is the force in micro-newtons that acts on the surface due to the sunlight?

F = 20.07 μN

Explanation:

given,                                            

intensity of sunlight = 667 W/m²

area of surface =  9.03 m²

speed of light = 3 x 10⁸ m/s

force = ?                                  

we know                                                                

force =

force =

F = 20.07 x 10⁻⁶ N

F = 20.07 μN
