The astronaut is in a state of weightlessness.

(A) When an astronaut is inside an orbiting satellite,both the astronaut and the satellite are in a state of free fall towards the Earth due to gravity. Since both have the same acceleration (the acceleration due to gravity at that altitude),the relative acceleration between them is zero. This condition is known as weightlessness. Therefore,the astronaut appears to be floating inside the satellite.

Motion of Satellites in Circular Orbits and Planets in Elliptical Orbits

$A$ planet moving along an elliptical orbit is closest to the sun at a distance $r_1$ and farthest away at a distance of $r_2$. If $v_1$ and $v_2$ are the linear velocities at these points respectively,then the ratio $\frac{v_1}{v_2}$ is
