Question

Orbital velocity is equal to √g/g+h how here it is √GMe/Re+h

Answer 1

Radius of orbit (R): Distance between satellite and centre of earth

Orbital velocity of a satellite orbiting with radius R is
v = √(GM / R)
[Note: Here R is radius of orbit (not radius of Earth)]

If satellite is at height H from earth’s surface then
v = √[GM / (Re + H)]
Here Re is radius of Earth
