# Studying Electron moving into uniform electric field?

Hi ,

I am trying to understand the outcome of below scenario.

An electron moving with a constant velocity v along x-axis enters a uniform electric field applied along Y-axis. Then the electron moves

1. with uniform acceleration along y-axis
2. without any acceleration along y-axis
3. in a trajectory represented as y=ax^2
4. in a trajectory represented as y=ax

I am speculating the answer is 3rd option. However, I am not sure why.

Many Thanks
Zaid
