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
- AZero since the astronaut feels weightless
- B$\frac{GMm}{(R + h)^2} < F_G < \frac{GMm}{R^2}$
- C$F_G = \frac{GMm}{(R + h)^2}$
- D$0 < F_G < \frac{GMm}{R^2}$
