1. The problem statement, all variables and given/known data "Two 100 kg lead spheres are suspended from 100-m-long massless cables. The tops of the cables have been carefully anchored exactly 1 m apart. What is the distance between the centers of the spheres? 2. Relevant equations F = (Gm1m2)/r^2 ???? 3. The attempt at a solution I'm not sure how this problem is related to Newton's theory and I am confused at this problem as I think the answer should simply be 1 meter because that is exactly how far the cables are anchored apart. Using the equation for F that I have provided I get 6.67x10^-7 N. This is the only equation we have really learned in class and I am unsure how this applies to the problem or how I use this to calculate the distance between the centers of the spheres. I feel dumb because this problem sounds so easy but I feel like I'm missing something. The book says it's a medium difficulty problem and that it requires material from earlier chapters but I'm not sure what. I would greatly appreciate any help on this to get me going. Thanks!
