Question: Physics HW Please Help

A string with a lead ball of mass m is slowly pulled upward through a small hole. Consider the work done on the system during this process. Find the change in energy and the frequency of this pendulum during this "adiabatic process", assuming the amplitude of the pendulum to be small.

Sorry I don't have a picture.

(Imagine the situation of the wire holding the chandalier in your home being slowly pulled up through a small hole through the roof while it is slowly oscillating in one dimension, or in a single plane.)
