Distances:

a =6.2 cm

b =7.7 cm

c =9.9 cm

E=3650 N/C

Question 1: What is VB - VA? (Between points A & B)I found this to equal 0 as the E field moves about the Y axis. This was correct.

Question 2: VC - VB? (between points B & C) I found this to be 281.05V using Delta V = E x -Delta S. This was also correct.

Question 3: VA - VC (between points C and A). I can not figure this out.

I'm assuming the pathagorian theorem comes into play, however if one of the sides = 0 for E, then the hypotenus would eqaul 3650.

What am I forgetting?
