Potential difference please help!
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?
Uel = qV
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.
