A pair of parallel metal plates are kept with a separation ' \(\mathrm{d}\) '. One plate is at a potential \(+\mathrm{V}\) and the other is at ground potential. A narrow beam of electrons enters the space between the plates with a velocity \(v_{0}\) and in a direction parallel to the plates. What will be the angle of the beam with the plates after it travels an axial distance L?
