(i) The Sun keeps away the Earth by pushing on it with sunlight. Determine the force applied by sunlight pressure on the planet Earth? Treat the Earth as a flat disk facing the Sun. Its radius is 6.37×106 m, and its albedo is 0.39. The intensity of sunlight at the orbit of Earth is 1380 W/m2.
(ii) The Sun attracts the Earth by pulling on it with the gravity. Determine the force applied by the gravity of Sun on the planet Earth? The mass of Earth is around 5.97×1024 kg, the mass of the Sun is around 1.99×1030 kg, and the distance between the two bodies is 1.50×1011 m.
