eText section 6.5 Familiarize yourself with the equation for Newton’s Law of Gravity and examples a) Calculate the gravitational force of the Sun on the Earth. b) Calculate the gravitational force of the Moon on the Earth. c) Calculate the ratio of part ‘a’ to part ‘b’

a) Calculate the magnitude of the gravitational force between the Earth and a mass of m = 5.70 kg on the surface of the Earth. The distance to the center of the Earth from the surface is 6.37×10^3 km and the mass of the Earth is 5.98×10^24 kg. b) Calculate the magnitude of the gravitational force between the Moon and a mass of m = 5.70 kg 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 3.76×10^5 km and the mass of the Moon is 7.36×10^22 kg. c) Calculate the ratio of the magnitude of the gravitational force between a mass of m = 5.70 kg on the surface of the Earth due to the Sun to that due to the Moon. The mass of the Sun is 1.99×10^30 kg and the distance from the center of the Sun to the surface of the Earth is 1.50×10^8 km.
