Answer :
Answer:
The value of radiation pressure is [tex]2.933 \times 10^{-8}[/tex] Pa
Explanation:
Given:
Intensity [tex]I = 8.8[/tex] [tex]\frac{W}{m^{2} }[/tex]
Area of piece [tex]A = 2.1 \times 10^{-4}[/tex] [tex]m^{2}[/tex]
From the formula of radiation pressure in terms of intensity,
[tex]P = \frac{I}{c}[/tex]
Where [tex]P =[/tex] radiation pressure, [tex]c =[/tex] speed of light
We know value of speed of light,
[tex]c = 3 \times 10^{8}[/tex] [tex]\frac{m}{s}[/tex]
Put all values in above equation,
[tex]P = \frac{8.8}{3 \times 10^{8} }[/tex]
[tex]P = 2.933 \times 10^{-8}[/tex] Pa
Therefore, the value of radiation pressure is [tex]2.933 \times 10^{-8}[/tex] Pa
