I have no clue. Can someone show me how to calulate this. Calculate the gravitational force between the Sun and the Earth. Use the following numbers. G = 6.67 x 10^(-11) m^3/kg/s^2, Mass of the Sun (M_sun) = 2.0 x 10^30 kg, Mass of the Earth (M_earth) = 6.0 x 10^24 kg, Distance between the Sun and the Earth (r) = 1.5 x 10^8km.
