MCQ (More than One Correct Answer)

-1

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

0 < F_G < $${{GMm} \over {{R^2}}}$$

$${{GMm} \over {{{\left( {R + h} \right)}^2}}}$$ < F_G < $${{GMm} \over {{R^2}}}$$

F_G = $${{GMm} \over {{{\left( {R + h} \right)}^2}}}$$
