Homework Help: physics

Posted by mymi on Sunday, October 30, 2011 at 9:11pm.

A carefully designed experiment can measure the gravitational force between masses of 9 kg. Given that the density of iron is 7860 kg/m3, what is the gravitational force between two 9.00-kg iron spheres that are touching?

I can determine the correct answer if the problem had some kind of distance between the two sheres, but without distance I do not know how to solve this problem. Help!
