(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How high above the surface of the earth should a rocket be

in order to have 1/100 of its normal weight? Express your answer

in units of earth radii.

2. Relevant equations

F=GMm/r^{2}

F=mg

3. The attempt at a solution

r = √(( 6.67 x 〖10〗^(-11) x 5.97 x 〖10〗^24 )/0.098)

then divide by 6.37*10^{6}

I asked for help from one of my friends and he emailed me this but I think he might have messed somthing up. I keep getting a really big number.

I also know the answer its 9 radii but i dont understand how to get that answer.
