(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

When an electron moves from A to B along an electric field line in the figure below, the electric field does 2.00 10-19 J of work on it.

What are the electric potential differences:

(a) VB - VA

(b) VC - VA

(c) VC - VB

2. Relevant equations

Ok so I know that the equation to use in this case is that of, [tex]\Delta[/tex]V = [tex]\frac{-W}{q}[/tex]

3. The attempt at a solution

I understand how to choose the equation I've chosen and how to get the right answer. What I don't understand is why the answers to (a) and (b) aren't negative when the equation shows that they should. Can anyone help?
