Calculate the magnitude of the gravitational force between the earth and a 2.200-kg mass on the surface of the earth. The distance to the center of the earth from the surface is 6370 km and the mass of the earth is 5.98 1024 kg. Calculate the magnitude of the gravitational force between the moon and a 2.200-kg mass on the surface of the earth nearest to the moon. The distance to the center of the moon from the surface of the earth is 376,000 km and the mass of the moon is 7.36 1022 kg Calculate the ratio of the magnitude of the gravitational force between a 2.200-kg mass on the surface of the earth due to the sun to that due to the moon. The mass of the sun is 1.99 1030 kg and the distance from the center of the sun to the surface of the earth is 1.50 108 km.
