Finding distance of approaching charges

Two large parallel copper plates are .05 meters apart and have a uniform electric field between them. An electron is released from the negative plate at the same time that a proton is released fro the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other.

I am seriously absolutely lost with this and don't even have a clue where to start.

Thanks for any help!!

In the uniform electric field, both will experience a force and thus an acceleration. The hitch which makes them not cross at an equidistant location is that the proton is much more massive than the electron.

Without any attempt from you, I can't help you so very much, but I would start at looking at the net force on each; hopefully this points you in the right direction.
