Homework Statement



Force of gravity on a spaceship is 900N. What is the force when mass is double and distance from earth center is 1/4 as far?

the answer i got was 28800N, but i just applied proportionalities apparent from in the equation [tex]F=G\frac{M_{e}m_1}{r^2}[/tex] . Is it the right answer?
