Physics equation manipulation question!?
How would the formula "Fg=(GMm/r^2)" be written so there is a ratio between Fg and r?
Having some trouble with my homework. Thanks for your time.

Fg / r = GMm/r^3
Which is not particularly useful if you ask me, are you sure that's what you mean?

Fg = G*M*m/r^2
here r is the distance between the centers of the two bodies of masses M,m
divide with r on both sides
Fg/r = G*M*m/(r^2*r)
Fg/r = G*M*m/r^3

Fg = GMm/r²
Fg/r = GMm/r³
You can't get the ratio Fg/r without having the r³ term.
Are you sure you have the question correct?
