Two Spherical Charge Distributions A spherical charge distribution p1 (r) has total charge Q1 and a second, nonoverlapping spherical charge distribution p2(r) has total charge Q2. The distance between the centers of the two distributions is R. Use the stress tensor formalism to prove that the interaction energy between the two is _ 1 Q1Q2 43:60 R Hint: It is not necessary to evaluate any integrals explicitly. VE
