014 (part 1 of 3) 10.0 points Consider two planets of mass m and 2m, respectively, orbiting the same star in circular orbits. The more massive planet is 7.2 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? 015 (part 2 of 3) 10.0 points What is the ratio 1:1 : 112 of the speeds of the two planets? 016 (part 3 of 3) 10.0 points What is the ratio T1 : T2 of the orbital periods of the two planets
