Asked by Greg

An electron is at the origin.
(a) Calculate the electric potential VA at point A, x = 0.410 cm.
(b) Calculate the electric potential VB at point B, x = 0.820 cm. What is the potential difference VB - VA?
Answered by Greg
In the book the examples they give have a charge to them, but they don't offer any help with this question because the don't list a charge of the electron
Answered by Damon
Your book does indeed surely give the charge on an electron
e = - 1.6 * 10^-19 Coulombs
Answered by Greg
In the equations listed they are refering to a point charge which is different then that of 1.6*10^-19. If I were to use that in the equation it would not work. The point charge in the example is 5.00*10^-6 C

never mind wrong question for the previous response. Thanks.
