Answer:
The radiation pressure exerted on the surface would be 6.3 x 10^8 Newtons per square meter, assuming complete absorption.
Step-by-step explanation:
The radiation pressure exerted on a surface can be calculated using the formula:
P = I * c
where P is the radiation pressure, I is the intensity of radiation, and c is the speed of light.
Substituting the given values, we get:
P = 2.1 * c
The value of the speed of light is approximately 3 x 10^8 meters per second.
P = 2.1 * 3 x 10^8
P = 6.3 x 10^8 N/m^2
Therefore, the radiation pressure exerted on the surface would be 6.3 x 10^8 Newtons per square meter, assuming complete absorption.
