Homework Statement
A satellite is in a circular orbit of radius R from the planet's center of mass around a planet of mass M.
The angular momentum of the satellite in its orbit is:
I. directly proportional to R.
II. directly proportional to the square root of R
III. directly proportional to the square root of M.
The correct answer apparently is II and III.
Homework Equations
The Attempt at a Solution
OK, I thought that since the satellite's angular momentum is mvR * sin(90), then its angular momentum would be directly proportional to its mass, velocity, and/or even the radius orbit.
I was thus the only thing that made sense.
Why is the correct answer II and III? Thanks so much in advance for the help!
