Assuming a particle to have the form of a ball and to absorb all incient light, find the radius of a particle for which its gravitational attraction to the sun is counterbalanced by the forces that light exerts on it. The power of light raiated by the sun equals `P = 4.10^(26)W`, and the density of the particle is `rho = 1.0 g//cm^(3)`.
