To determine the number of electrons on a sphere charged to -5x10^-6 C, divide the total charge by the charge of a single electron, which is -1.6x10^-19 C. This calculation reveals that there are approximately 3.125x10^13 electrons on the sphere. The discussion briefly shifts to a humorous note about the cost of CDs, with a mention of having $1,250 to purchase them. However, the primary focus remains on the calculation of electrons related to the charged sphere. The conversation highlights both a scientific inquiry and a light-hearted commentary on finances.
