Questions
The incident intensity of an a horizontal surface at sea level from sun is about 1 kW/m2. Assuming that 50% of this intensity is reflected and 50% is absorbed, then the radiation pressure on this horizontal surface
detailed solution
Correct option is A
Total radiation pressure on the surfaceP=I/2C+2I/2C=I2C+2I2C=3I2CP=32 x 10003 x 108=5 x 10-6 pascalTalk to our academic expert!
