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 3000 N/C. Determine the electric potential difference (a) VB - VA between points A and B, (b) VC - VB between points B and C, and (c) VA - VC between points C and A. http://edugen.wiley.com/edugen/courses/crs2216/art/qb/qu/c19/ch19p_56.gif 2. Relevant equations 3. The attempt at a solution I was able to solve the first two parts of this problem easily but I am hung up on how the angle of the triangle plays into this. I know A is zero because they are on the same equipotential field. B I solved by converting the distance to meters and multiplying that by the magnitude of the electric field. For C I know that it will be a combination of both the vertical and horizontal direction and I know that I am supposed to find that by using sin or cos but I just cant seem to put it together!
