Homework Help: Physics

Posted by Lindsay on Sunday, December 16, 2007 at 8:40am.

Consider a spaceship located on the Earth-Moon center line (i.e. a line that intersects the centers of both bodies) such that, at that point, the tugs on the spaceship from each celestial body exactly cancel, leaving the craft literally weightless. Take the distance between the centers of the Earth and Moon to be 3.90E+5 km and the Moon-to-Earth mass ratio to be 1.200E-2. What is the spaceship's distance from the center of the Moon?

I'm still a little confused on what I have to do for this one. Which distance equation do I need to use??
