To solve the problem we will require the concept of Force as a definition of pressure and Area, and the concept of light pressure itself determined by the relationship between intensity and the speed at which light travels. We will match the terms and find the desired force value,
Here,
P = Pressure
A = Area
Pressure due to the light of the sun will be
Here,
I = Intensity
c = Speed velocity
Equation both therms we have that
We have a circular area then
Replacing with our values (Adding the radius of the Earth)
Therefore the Force on Earth due to radiation pressure is 
Answer:
139 N

One example is that when their food catches fire in a cooking pot or pan, it is advisable to smother the fire by covering the fire with a blanket rather than douse the fire with water. DOeing the later will only aggravate the fire. Knowledge of basic science dictates that oil and water are immiscible liquids the oil will continue to burn even as the water is poured into the oil. More so, as the water violently evaporates due to the heat, it spreads the burning oil and hence spreads the fire.
