7 0. (a) Using d = 2 m, we find the potential at P : V P = 1 4 πε 0 +2 e d + 1 4 πε 0 -2 e 2 d = 1 4 πε 0 e d . Thus, with e = 1.60 × 10 19 C, we find V P = 7.19 × 10 10 V. Note that we are implicitly assuming that V 0 as r . (b) Since U = qV , then the movable particle's contribution of the potential energy when it is at r = is zero, and its contribution to U system when it is at P is (2
