## 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!
