Document Summary
E" = ( ext , ey y , ez "t ) Chapter 25: potential energy of a system of charged particles total potential energy is the sum of potential energy of all 2 particle pairs " Recall the electric pe of a particle is - work needed to bring this p from as final to. Work = work q , ( step 1) + work q . ( in the presence of q . + work 9 , ( in the presence of q , and q . ) W z = q , [ vat 3 due to i t v at 3 due to 1 ] Potential of a charged isolated conductor (qq. y-iaef. tt git) Inside a conductor no work done to move charge .
