Question
The orbital velocity of a planet does not depend upon:
- The radius of the path
- Mass of the Sun
- Mass of the planet
- Acceleration due to gravity
Hint:
Orbital velocity of a planet can be found out by balancing gravitational and centripetal forces.
The correct answer is: Mass of the planet
The orbital velocity of a planet is given by
where,
G - Acceleration due to gravity,
M - Mass of the sun,
r - Radius of the orbit.
Hence, the orbital velocity of a planet does not depend upon mass of the planet (m).
