momerntom of photon (p) equals E/c. Force equals delta p/delta t , which in this case is p / delta t because the earth stops it. So the energy per sec (which you can look up) devided by c is the force

Hi. This link does a pretty good job of explaining why light DOES have a force : http://www.newton.dep.anl.gov/askasci/phy00/phy00222.htm
You would need to calculate the area and consider that the spherical shape in not the best collector of energy to find the actual total force.

I'm not certain of your parameters, but I can tell you that light exerts a minuscule force on the earth. Most of the energy in sunlight is lost to ionization.

Mass is only required for kenetic or potential energy. Thermal, nuclear, electric, etc energies are all independent of mass.

.none.mass determines force.
