 Homework Statement:

A 60 kg person stands on each of the following planets. On which planet is their weight the greatest?
Planet A mass M and Radius 3R
Planet B mass 2M and Radius 2R
Planet C mass 2 M and Radius 3 R
Planet D mass 3 M and Radius 3R
 Relevant Equations:

A) Planet A
B) Planet B
C) Planet C
D) Planet D
E) Planets B and D
F) The weight is the same on all
Can someone please verify if my reasoning is accurate?
I chose E) Planets B and D because they both have the same ratio of mass to radius which is the lowest of all the other planet options. Due to the fact that they have mass and radius evened out the gravitational pull will pull weight down more than any pf the other planets.
