Решение задачи по физике раздел 71 пункт 66 электро

66. An electrostatic field is created by a point charge Q = 20 nC. Determine: 1) the work done by the forces of this field when the charge is moved Q1 = 10 nC from a point with a potential of φ1 = 500 V to a point with a potential of φ2 = 200 V; 2) the distance between these points.
