Consider two planets of mass m and 2m,
respectively, orbiting the same star in circular
orbits. the more massive planet is 4.5 times
as far from the star as the less massive one.
what is the ratio f1 : f2 of the gravita-
tional forces exerted on the star by the two
planets?
what is the ratio v1 : v2 of the speeds of the
two planets?
what is the ratio t1 : t2 of the orbital periods
of the two planets?
