Compare the gravitational forces exerted by the Sun and the Moon on the Earth. Which one exerts a greater force on the Earth? (Given: mass of the Sun, Ms=4×1031 kg; the mass of Moon, Mm=6.3×1022 kg; distance between Sun and Earth, r=1.3×1012 m and the distance between Moon and Earth,r=4.5×108 m)
What would happen to earth, if sun suddenly vanishes? (Neglect the gravitational force due to other planets)
