I was able to calculate the potential difference pretty easily but I got the second part wrong. I thought the higher potential would be at the point x=2 but the book says the origin. Here is my reasoning, please tell me where I'm going wrong:

Since the electron is decelerating along the positive x-axis, it is experiencing a force due to an electric field pointing in the -x direction. Since electric potential decreases as you move along the direction of an electric field, the origin should be at lower potential.

Thanks.
