WebJun 20, 2016 · The most natural things that comes to my mind when thinking about such a problem is that the effective force should be a restoring force for circular orbits to be stable. f e f f ( r) = l 2 μ r 3 − f ( r) = 0, for orbit to be circular. f e f f ′ ( r) < 0, for orbit to be stable. Assuming a power law, f = K r n, for the central force ... WebStudent handout: Effective Potentials.
