Question

If a satellite is revolving near the earth's surface, then its orbital velocity depends upon

• A. The mass of the satellite
• B. The radius of the earth
• C. The radius of the orbit
• D. The mass of the earth

Answer 1

The correct option is B The radius of the earth

Orbital velocity is the velocity given to the body to keep it in orbit.it is given as:
$v_{orbit}=\sqrt{\frac{GM}{r}}$
so,If a satellite is revolving near the earth's surface, then its orbital velocity depends upon the radius of the earth.
hence,option B is correct.
