how we can caculate mass of cathode rays by using magnetic field
Answers
Answer:
Thomson measured the mass of cathode rays, showing they were made of particles, but were around 1800 times lighter than the lightest atom, hydrogen. ... It was quickly recognized that they are the particles that carry electric currents in metal wires, and carry the negative electric charge of the atom.
Answer:
The mass-to-charge ratio (m/Q) is a physical quantity that is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics. It is used to calculate mass of cathode rays by using magnetic field
Explanation:
When Thomson's data are converted to SI units, the charge-to-mass ratio of the particles in the cathode-ray beam is about 108 coulomb per gram. Thomson found the same charge-to-mass ratio regardless of the metal used to make the cathode and the anode.
