It was 2.6m...I fixed it. I found that the answer was just 0.0868 not -0.0868. My teacher said the equation was Work = -\DeltaPE, but I found it some place else that shows it as just Work = \DeltaPE. Which is correct?

Homework Statement Two point charges Q1 = 3.3 µC and Q2 = 7.6 µC are initially very far apart. They are then brought together, with a final separation of 2.6 m. How much work does it take to bring them together? Homework Equations \DeltaPE = ( k Q1 Q2 ) / r Work = - \DeltaPE k= 8.99 e 9...

ok...I removed the a from the X and Vo from the Y and got the answers correct...are the motion equations different in this way with electric fields? My book sucks!

I thought the motion equations were (the ones we are talking about) Vx = V0 + at Y=Y0 + V0t + 1/2 at^2

Here is a list of all the questions...I am only having trouble with d and first part of e (a) How long does it take the electron to travel the length of the plates? t = (b) What are the magnitude and direction of the electric force on the electron while it is between the plates? magnitude...

Thanks, I found the acceleration and was trying to do that...look at my work now...I edited my post since you replied. I have this online homework system and it is not taking my answers...not sure if my logic is just way off.

Homework Statement An electron is traveling through a region between two metal plates in which there is a constant electric field of magnitude E directed along the y direction as sketched in the figure below. This region has a total length of L, and the electron has an initial velocity of v0...
