An electron of mass me and charge q=−e is injected horizontally midway between two very large oppositely charged plates. The upper plate has a uniform positive charge per unit area +σ and the lower plate has a uniform negative charge per unit area −σ . You may ignore all edge effects. The particle has an initial velocity v⃗ 0=v0xˆ . What is the y-component of the position of the particle when the particle reaches the plane defined by x=L?
