A planet orbits the sun in a circular path. If the radius of the orbit is doubled, what happens to the angular momentum of the planet if its speed remains constant?
Doubles
Halves
Remains the same
Quadruples
Angular momentum L = mvr, so if the radius is doubled and speed remains constant, angular momentum doubles.
