28.12 A 20 000 N C-1 uniform electric field does +5000 J of work on a +0.20 C charged object. (a) Did the charged object move in the direction of the electric field or against it? (b) : (c) How far did the object move? What was the change in electrical potential through which the object moved? (d) If the object was initially at at point with an electrical potential of -2000 V, what was the electrical potential at its end point?
