Q. Two planet have same density but different radii . the acceleration due to gravity would be (1) Same on both planets (2) Greater on the smaller planet (3) Greater on the larger planet (4) Dependent on the distance of planet from the sun. Share with your friends Share 0 Sanjay Upadhyay answered this Dear studentThe accelaration due to gravity is given byg=GMr2Here we can see that g is independent of density but depends on radius.Now since gis inversely proportinal to r then the greater radii will have smaller g.Hence option (2) is correct.regards -1 View Full Answer Shafana answered this Option 2 Since r square is inversly proporttional to g. g = GM/r sq. When radius is small g is high. -1
