Tag: orbital velocity of a satellite

What is the orbital velocity of a satellite orbiting very close to the surface of earth?

A. 7.92 km/s
B. 9.8 km/s
C. 11.2 km/s
D. 14.8 km/s

Answer

Correct Answer: A. 7.92 km/s


Detailed About MCQs

In this case, the radius of the orbit will be nearly equal to the radius of earth. The orbital velocity of a satellite orbiting very close to the surface of earth is 7.92 km/s.

An orbital velocity of a satellite does not depend on:

A. Radius of the planet
B. Mass of the planet
C. Radius of orbit
D. Mass of the satellite

Answer

Correct Answer: D. Mass of the satellite


Detailed About MCQs

An orbital velocity of a satellite does not depend on the mass of the satellite. It depends on the mass and radius of the planet around which it is orbiting. Also, it depends on the radius of the orbit or the height of the satellite.
