## Homework Statement

How much work does the electric field do in moving a proton from a point with a potential of +260 V to a point where it is -48.0 V? Express your answer in electron volts.

## Homework Equations

V = p(A) - p(B)

## The Attempt at a Solution

V= 260 [v] - (-48.0[V]) = 3.08×102 [V]

Right answer: -3.08×102 [V]

I got the right answer, but the wrong sign. I'm not sure if this has anything to do with a proton moving from a positive to negative potential (this would only be important if it was moving from a positive to negative charge?).

Why would the answer be negative?
