WebSir Joseph John “J.J.” Thomson, OM, FRS (December 18, 1856 – August 30, 1940) was a British physicist and Nobel laureate, credited with the discovery of the electron, the isotope, and the invention of the mass spectrometer. He was awarded the 1906 Nobel Prize in Physics for his work on the conduction of electricity in gases. WebThen the downward force Ee due to the electric field is balanced by the force Bev due to magnetic induction where e is the charge of the cathode ray particle and v is the velocity of the cathode rays.
