Charge to mass ratio electron
Webmakes an electron move along the circular trajectory; the radius of this trajectory rcan be found from Newton’s Second Law: m v2 r = evB (1.2) From this equation we obtain the expression for the charge-to-mass ratio of the electron, expressed through the experimental parameters: e m = v rB (1.3) WebUsing this apparatus, Thomson determined the charge-to-mass ratio of the electron, e/m. The determination of the charge of the electron awaited the work of Millikan who measured the electron charge in 1909 with his oil drop experiment. With the combined results of Thomson and Millikan, a value for the electron mass was obtained - a value far ...
