August 12, 2010 37 Electric Potential Energy for a System of Particles ! So far, we have discussed the electric potential energy of a point charge in a fixed electric field ! Now we introduce the concept of the electric potential energy of a system of point charges ! In the case of a fixed electric field, the point charge itself did not affect the electric field that did work on the charge

Unformatted text preview: ! Now we consider a system of point charges that produce the electric potential themselves ! We begin with a system of charges that are infinitely far apart This is the reference state, U = 0 ! To bring these charges into proximity with each other, we must do work on the charges, which changes the electric potential energy of the system Thursday, September 16, 2010...
