Calculate how far an astronaut would need to be away above the Earth in order for his weight to be 0.01 his weight on the Earth's surface.
Where did I go wrong?
Calculate how far an astronaut would need to be away above the Earth in order for his weight to be 0.01 his weight on the Earth's surface.
The question asks "above the Earth" so I subtracted the radius of the Earth.What is your second last step involving, and what is the correct answer?
The value you have gotten is correct for the question asked.
Easy way to check would be to sub in your 'r' value in the eqn 'g = GM/r^2'
Your r value comes out to a g of around 0.098 (which is 0.01 of g on earth)
Their r value comes out to a g of around 9.268. WRONG.
I did the working and got the same answer as you, I also tried a different method and still got the same answer. I think you're right the book must be mistaken.
YeaI got the same answer... and everything you did looks right . Need another person to determine if the book is wrong again
