em value for electron is the ratio of charge on an electron to its mass. Charge on an electron = 1.602 × 10−19 C. Mass of an electron = 9.109 × 10−31 Kg.

Introduction. In this experiment you will measure e/m, the ratio of the charge of an electron to the mass of an electron. The currently accepted value for e/m is 1.758820 × 1011 C/kg.

In particle physics, the electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron.
