F B = q v B. where: e and q - the charges of the electron, V - the acceleration potential, v - the velocity the charges travel at, F B - the force due to the magnetic field, and B - the external magnetic field. Together, these equations give the e/m ratio: e m = 2 V r 2 B 2. emory decatur hospital infusion centerWebThe mass-to-charge ratio of particles in the beam. JJ Thomson measured the beam's deflection in electric and magnetic fields. Reasoned that amount of beam's deflection depended on mass of particles and their electric charge. Greater particle mass = greater inertia, less deflection. Greater particle charge = greater force, greater deflection. dr alan altham

"WebJ.J. Thomson experiment had the following observations in a series of experiments. The rays were deflected by the electric charge, proving beyond doubt that the rays were made up of charged particles carrying a negative charge. The charge of the mass ratio of these negatively charged particles is same irrespective of the gas taken in a tube. " - Jj thomson charge to mass ratio
