Calculate, using Newton's law of gravity, the size of the force of attraction between the Earth and a mass of 5.0kg on the Earth. Data: Distance to the center of Earth from thesurface = 6370 km. Mass of Earth = 5.98*1024 kg. Gravitational constant (G = 6.67 times 10-11 Nm2/kg2).
Calculate, using Newton's law of gravity, thesize of the force of attraction between the moon and a mass of 5.0kg on the earth surface nearest the moon. Data: Distance to themoon from surface of the earth = 376,000 km. Mass of moon = 7.36times 1022 kg.
Calculate, using Newton's law of gravity, theratio of the strength of the force of attraction of a mass of 5.0kg on the earth's surface by the sun to that by the moon. Additional Data: Mass of sun =1.99 times 1030 kg. Distance from the sun to the surface of Earth = 1.50 times108 km.
