Question: Calculate the earth's gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 k/n above the earth's surface, and then compare

Calculate the earth's gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 k/n above the earth's surface, and then compare this value with his weight at the earth's surface. In view of your result, explain why we say astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. Is it because the gravitational pull of the earth is negligibly small?
