Question

An astronaut of mass m is working on a satellite orbiting the earth at a distance h from the earth's surface. The radius of the earth is R , while its mass is M . The gravitational pull F G on the astronaut is, Zero since astronaut feels weightless, G M m R + h 2 F G G M m R 2, F G = G M m R + h 2, 0 F G G M m R 2

MARKS App · Accepted Answer

As distance of the astronaut from the centre of the Earth is = R + h Therefore, gravitational force = G m 1 m 2 R + h 2 = G M m R + h 2
