Homework Help: Force of gravity problem.

  1. Mar 15, 2007 #1
    1. The problem statement, all variables and given/known data

    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?


    3. The attempt at a solution

    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?
