There is an potential different between the gap which will form electric field
You can calculate acceleration
And you can calculate how the charge will move (velocity,displacement)from acceleration.
thx , but how can I study the effect of magnetic field in the gap ??
and how the charge particle will move in the gap ?? circular motion or straight one ?
does it effect with the magnetic field ??
