Electron's Charge to Mass (e/m) Ratio

Electron's Charge to Mass (e/m) Ratio

In this experiment you will be able to calculate the ratio of the electron charge to its mass. To do this, you will use the laws of physics that describe the motion of charged particles in a magnetic field. A magnetic force is applied to electrons entering the magnetic field perpendicularly. This force causes the electrons to follow a circular trajectory.
