Question

Quizplus · Accepted Answer

A resonance occurs when the orbital period of a ring particle is equal to the ratio of integers with the orbital period of the satellite. Therefore, the ratios for each option are:
A) 4:1
B) 17:5
C) 2:1
D) 3:1

Only option B does not result in a ratio of integers, indicating that there would not be an effective resonance with the given satellite.
