Calculate the magnitude of the gravitational force between the Earth and an m = 6.00 kg mass on the surface of the Earth. The distance to the center of the Earth from the surface is 6.37×103 km and the mass of the Earth is 5.98×1024 kg.
B)Calculate the magnitude of the gravitational force between the Moon and an m = 6.00 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 3.76×105 km and the mass of the Moon is 7.36×1022 kg.
C)Calculate the ratio of the magnitude of the gravitational force between an m = 6.00 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.

1. F = m*g so 6*9.81
2. A= G*distance to moon*distance to earth
B = Mass of the moon. So your answer is A/B
