At what altitude above the Earth's surface is the acceleration due to gravity equal to g/3?
but it is saying this is not correctHomework Equations
ag=G Me/(Re+H)^2
The Attempt at a Solution
I solved for H and got H=√3 Re-Re
using this i got 17*10^6

D H
I solved for H and got H=√3 Re-Re
using this i got 17*10^6
for re i used 6.37*10^6m
the answer is also sopossed to be in meters i started with ag=g Me/(Re+H)^2
then plugged in 1/3*9.8=G Me/(Re+H)^2
I reduced that to ag=1/(Re+H)^2=1/3(1/Re^2)
from there i got
(Re+H)^2=3Re^2
Re+H=sqrt(3)*Re
H=sqrt(3)Re-Re
Your derivation looks okay, so you must be having finger problems with the calculator
