Two planets, Fibblestib and Dimble, orbit a single star. The gravitational force from the star on planet Fibblestib is five times the force from the star on planet Dimble. Also, planet Dimble has three times the mass of planet Fibblestib. What is the ratio of the two planets’ orbital radii RFibblestib/RDimble?
