The solar constant represents the average energy per unit area received from the Sun on Earth, which is 1.4 × 103 W/m2. Small particles can be expelled from the solar system due to the radiation pressure of sunlight. Given that the specific gravity of the particles is 5, what is the radius of the largest particle that can be ejected?
