Question

An electron is at the origin.

An electron is at the origin. (a) Calculate the electric potential VA at point A, x = 0.960 cm. (b) Calculate the electric potential VB at point B, x = 1.070 cm. Your response differs from the correct answer by more than 10%. Double check your calculations. V What is the potential difference VB - VA? Your response differs from the correct answer by more than 100%. V (c) Would a negatively charged particle placed at point A necessarily go through this same potential difference upon reaching point B? Explain

Explanation / Answer

A. Electric potnetial V = KQ/r

so here r = 0.0096 m

so VA   = 9e9 *1 .6e-19/(0.0096)

VA = 1.9 *10^-6 V
----------------------------------

VB = 9e9 *1.6e-19/(0.01070)

VB = 1.345 e-6 V

---------------------------------

VB-VA = 1.345-1.9 = -0.55 uV
