When you use the formula , is meant to be the distance between the charged plates, not the distance between a charged plate and the particle.

Also you should realise that a characteristic of a magnetic field between two charged plates is that it is equal at all points between the charged plates. Therefore no matter where you place the charged particle, the force it experiences will not change. Hence the force that the charged particle would experience is .
