Potential difference in an electron

[mathcrzy]

Homework Statement

An electron acquires 3.01e-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates?
_____V

Homework Equations

- (Wba / q ) = V

The Attempt at a Solution

- (3.01e-16 / 1.6e-19) = V
V = -1881.25

What does the product of the charge of the electron and the pd of the plates give you?

 

[mathcrzy]

would those give me the velocity between the two plates?

Why do you need the velocity for?
