Homework Help: Physics

Posted by Lindsay on Saturday, December 15, 2007 at 10:45am.

Three very small spheres are located along a straight line in space far away from everything else. The first one (with a mass of 2.43 kg) is at a point between the other two, 10.60 cm to the right of the second one (with a mass of 5.17 kg), and 20.70 cm to the left of the third one (with a mass of 6.20 kg). Calculate the magnitude of the net gravitational force it experiences.

I'm not sure how to solve these types of problems, given only mass and distance. Plus, the "in space" part sort of throws me off...
