1. The problem statement, all variables and given/known data

It takes 3.3 μJ of work to move a 34.26 nC charge from point A to B. It takes -3.3 μJ of work to move the charge from C to B. What is the potential difference VC-VA?

2. Relevant equations

Uel = qV

3. The attempt at a solution

Don't I just find the difference between A and C?

Vc = Uelc * qc = 1.13x10^-13

And Va would be the same so I know I am not understanding this.
