Which fact is represented by the pictures of an astronaut floating in a satellite?

The orbit of a geostationary satellite is circular. The time period of the satellite depends on $(i)$ mass of the satellite,$(ii)$ mass of the earth,$(iii)$ radius of the orbit,and $(iv)$ height of the satellite from the surface of the earth.

The weight of an astronaut,in an artificial satellite revolving around the earth,is

Why does a satellite not have an escape velocity?

$A$ satellite is moving around the earth with speed $V$ in a circular orbit of radius $r$. If the orbital radius is decreased by $2\%$,the speed of the satellite will
