Question:

(a) At one-third the original distance from a positive point charge, by what factor is the electric potential changed: (1) 1/3, (2) 3, (3) 1/9, or (4) 9? Why?
(b) How far from a +1.0-μC charge is a point with an electric potential value of 10 kV?
(c) How much of a change in potential would occur if the point were moved to three times that distance?
