This relatively simple problem shows that they apply to any collection of masses, even two completely non-interacting masses. text/html 2012-03-23T15:36:50-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:hw:cfhw:cfhweffpot?rev=1332542210 Homework for Effective Potential Not all central forces are Coulombic. What happens if you change from an attractive to a repulsive potential? This problem has many parts. Don't forget your lessons from introductory physics!

In this problem students solve the differential equation for the Laguerre Polynomials. The question is worded so that students see this as a practice problem on series solution methods rather than specifically the Laguerre equation which they can look up.
