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

Question

$\begin{array}{1 1}(1) Zero\; since\; astronaut\; feels\; weightless \\ (2) 0 < F_G < \frac{ GMm }{R^2} \\ (3) \frac{GM_m}{(R+h)^2} < F_G < \frac{GM_m}{R^2} \\(4) F_G = \frac{GM_m}{(R+h)^2}\end{array}$
