Consider a point charge q = 0.93 JC, point A at distance dj = 1.7 m from q, and point B at distance d2 = 1.0 m. (a) If A and B are diametrically opposite each other, as in Figure (a), what is the electric potential difference VA - VB? (b) What is that electric potential difference if A and B are located as in Figure (b)? do + B A (a ) (b) (a) Number i Units (b) Number i Units
