1. The problem statement, all variables and given/known data The drawing shows a uniform electric field that points in the negative y direction; the magnitude of the field is 1600 N/C. http://www.webassign.net/CJ/p19-32.jpg a) Determine the electric potential difference VB - VA between the points A and B. The answer here is 0 V. (b) Determine the electric potential difference VC - VB between the points B and C. V (c) Determine the electric potential difference VA - VC between the points C and A. V 2. Relevant equations delta(V)=-Ed 3. The attempt at a solution For A, delta(V)= -(1600N/C)(.06m)- -(1600N/C)(.06m)= 0V For B, I tried delta(V)= -(1600)(.08)- -(1600)(.08)=0V which is an incorrect answer according to my online submission. C hasn't been attempted yet, because I'm going to need to make sure I'm doing this correctly. I'm not sure how to determine the different potentials when I have no values for the point charges... Can anyone offer some assistance? Not looking for answers, just guidance that will get me on my way. Thanks!
