Question

Two satellites are orbiting earth at different altitudes. Which satellite orbits at a higher speed v around earth?

Answer 1

Low satellite has high orbital velocity

Step-by-step explanation:

let v be the orbital speed of the satellite orbiting at a height h is given by

`v=\sqrt{(GM)/(R+h)}`

where, M be the mass of planet, r be the radius of planet and h be the height of planet from the surface of planet.

here we observe that more be the height lesser be the orbital velocity.

So, a satellite which is at low height has high orbital velocity.
