Question
(a) If these points are diametrically oppositeeach other, as in Figure (a), what is the electricpotential difference VA -VB?1 V
(b) What is that electric potential difference if points Aand B are located as in Figure (b)?
2 V Explination Please. Consider a point charge q = 2.0 Mu C, point A at distance d1 =8.0 m from q, and pointB at distance d2 = 2.0 m. (a) If these points are diametrically oppositeeach other, as in Figure (a), what is the electricpotential difference VA -VB? (b) What is that electric potential difference if points Aand B are located as in Figure (b)? Explination Please.
Explanation / Answer
potential at either point is V = k q /r so . at point A: V = 8.99 x 109 * 2.0x 10-6 / 8.0 = 2247.5 Volts . at point B: V = 8.99 x 109 * 2.0x 10-6 / 2.0 = 8990 Volts . (a) Va - Vb = 2247.5 -8990 = -6742.5 V . (b) same answer... potential does not depend ondirection -6742.5 VRelated Questions
