The charge to mass ratio of the electron was first measured by J. J. Thompson in 1897. This is often referred to as THE discovery of the electron. Thompson used a combination of electric and magnetic fields in his experiment. We will defer the magnetic part of the experiment to later in the course, and examine the electric part now. The device he used sent a beam of electrons between two plates, as shown below, between two plates. The initial velocity, vo of the beam was horizontally to the right. Thompson then measured the deflection, y, of the beam from where it exited the plates with the electric field turned off. Thompson also used a magentic field, which allowed him to determine the initial velocity. For now, lets find an expression for the charge to mass ratio in terms of this velocity and the other parameters. y JE Plate Plate m, Q x=L x (a) Assume that the weight of the electron can be neglected, so that the only force in play is the electric force.
