1. The problem statement, all variables and given/known data The moon has a mass M = 7.36e+022 kg and an average radius R = 1740 km. for part a)I solved for the gravitational acceleration on the surface of the moon= 1.62 m/s^2 An object on Earth weighs 64 N. b) What is the weight of this same object on the moon? Answer: 10.568 N I am stuck on part c. of the problem... c) How many earth radii must this same object be from the surface of the earth if it is to weigh the same as it does on the surface of the moon? 2. Relevant equations g= GMe/Re^2 3. The attempt at a solution What I did was, I tried to use the g(moon)= 1.62= GMe/(nRe)^2 where G= 6.67e-11 Me= 5.97e24 Re=6.37e6 And solved for n= number of earth radii= 2.461, but that isn't correct. Can someone tell me what I did wrong? Thank you.
