What is the work required to move an electron in an electric field?

Homework Statement

What work is needed to move an electron from (0,5m,0) to (0,0,8m) in an electric field of E = {25, -30, 0} x 10^3 V/m?

Homework Equations

W = Change in U = Q* Change in V

The Attempt at a Solution

I calculated Change in V = -E* change in r. Change in r I got (0,-5, 8). Then I took that and multiplied it by the Electric Field and got 0-(30)(-5)-0 = 150 x 10^3.

Now, how can I find charge Q? If I knew how to find charge Q I could multiply it to Change in V that I just calculated above and it would give me W.

you have an electron .. so your chage Q should be the charge of electron which is 1.6x10^-19 c ..

Ahh thanks...read the question too fast. Should have slowed down and payed attention.
