Calculate, using Newton's law of gravity, the magnitude of the force of attraction between the Earth and a mass of 16.000 kg on the Earth's surface. The distance to the center of the Earth from the surface is 6370 km. The mass of the Earth is 5.98 x 1024 kg. Gravitational constant G = 6.67 x 10-11 Nm2/kg2.
Calculate, using Newton's law of gravity, the magnitude of the force of attraction between the Moon and a mass of 16.000 kg on the Earth's surface nearest the Moon. The distance to the Moon from surface of the Earth is 376,000 km. The mass of moon is 7.36 x 1022 kg. Gravitational constant G = 6.67 x 10-11 Nm2/kg2.
