Thanks for your response. However, I am not sure I understand you. Are you telling me that once I have this equation: rA=krB that I need to solve for k in order to get the ratio between rA and rB? Also, what do you mean by "use the volume ratio to work out what mA is in terms of k and mB"? What...

Thank you for your response. And, yes, by gravity I mean "the force of gravity at the planet's surface." I also understand just about everything you said. I understand that the force of gravity is proportional to mass, which is proportional to volume, which is proportional to radius cubed, etc...

It would be greatly appreciated if someone could help me solve this problem. There are two objects, let's call them object A and object B. Assume that object B is the Earth and object A is some other planet. If object A has 10 times the gravity of object B (Earth) and assuming object A and...
