Walker, Halliday & Resnick β Electromagnetic Waves: Problem 28
28 Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of $1.4\text{ kW/m}^2$. (a) Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sunβs rays and that all the incident energy is absorbed, calculate the force on Earth due to radiation pressure. (b) For comparison, calculate the ratio of that force to the force due to the Sunβs gravitational attraction.
