Homework Statement
This is actually just a minor part of a larger problem - I need to find the potential energy of a string of mass m and length L that is hanging over the edge of a table.
Homework Equations
The Attempt at a Solution
If we define V = 0 at the level of the talbe, then the potential energy of a mass element dm below the able is given by V = -gydm where y is the height of dm below the table. But here I blank - how can I use this to find the total potential energy o hte cord?
