The momentum of a photon is E/c

a) Calculate the momentum per second delivered to the outer layers of a 100 solar luminosity star if all photons are absorbed in that layer.

b) How does the force on the layer compare with gravitational force on the layer if the layer has a radius of 100 solar radii, and a mass of .1 solar mass and the rest of the star has a mass of 1 solar mass
