A satellite is orbiting close to the surface of the earth, then its speed is
A satellite is revolving in a circular orbit at a height ‘h’ from the earth’s surface (radius of earth R ; h<<R). The minimum increase in its orbital velocity required, so that the satellite could escape from the earth’s gravitational field, is close to : (Neglect the effect of atmosphere.)
If a satellite is orbiting the earth very close to its surface, then the orbital velocity mainly depends on
