The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 ×
P a. So, the correct option is (b).
Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data
Solar constant ( S ) = 1350W / m ^2
Now, the radiaton pressure is given by
P = 2 S /c
where c is the speed of the light
P = 2 × 1350 /3 × 10 ^8
P = 9 ×
P a
For a black surface, P = 4.5×
P a
Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 ×
P a
