Question

When an electron moves from A to B along an electric field line in the figure, the electric field does 5.25 × 10-19 J of work on it. What are the electric potential differences (a)VB - VA, (b)VC - VA, and (c)VC - VB? 

Answer 1

Student,

Without the picture to look at it, it is difficult for a tutor to answer the question. But in any case, if you move a charge q from a point where the potential is V₁ to a point where it is V₂, the electrical work done is

W = -qΔV = q(V₁ - V₂)

Now apply this equation to the configurations in the picture, and solve for ΔV.
