Question

Assume the intensity of solar radiation incident on the upper atmosphere of the Earth is 1 370 W/m2 and use data from as shown as necessary. Determine (a) the intensity of solar radiation incident on Mars, (b) the total power incident on Mars, and (c) the radiation force that acts on that planet if it absorbs nearly all the light. (d) State how this force compares with the gravitational attraction exerted by the Sun on Mars. (e) Compare the ratio of the gravitational force to the light-pressure force exerted on the Earth and
the ratio of these forces exerted on Mars, found in part (d).
