How can you answer this with a word or phrase?

anonymous · Answer

i believe the answer would be 9.02 * 10^6 is that correct?

anonymous · Answer

or i guess it would be (9.02 * 10^6)-R

The force of gravity is $$F _{g}=\frac{ m m _{earth} G }{ r ^{2} }=m g \rightarrow g=\frac{ m _{earth} G }{ r ^{2} } \rightarrow r=\sqrt{\frac{ m _{earth}G }{ g }}$$ were g is 4.9 meters per second square, m earth is the mass of the earth, G is the gravitational constant and r is the height
