Electric Potential Energy for a System of Particles (3) ï§ So, the electric potential energy of this two charge system is U ï½ q2V1 (r ) kq1 where V1 ( r ) ï½ r ï§ Hence the electric potential of the two charge system is q1 r kq1q 2 Uï½ r q2 ï§ If the two point charges have the same sign, then we must do positive work on the particles to bring them together. ï§ If the two charges have opposite signs, we must do negative work on the system to bring them together from infinity. 1/24/07 184 Lecture 10 19
