Charge-to-mass ratio; kinetic energy; momentum; rest mass; relativistic mass; charged particles; magnetic deflection; Lorentz force law; velocity transformation; magnetic field; electric field; mass-energy equivalence; cathode rays.
In this investigation, experiments, by J. J Thomson, on cathode rays, are briefly reviewed. And the treatment of the charge-to-mass ratio and the relation between mass and energy generally are analyzed in detail, within the theoretical framework of classical physics and relativistic physics, respectively. And accordingly, it's concluded that precise procedures and rigorous mathematical formulas for transforming velocity values from classical physics to relativistic physics, and vice versa, undermine and ultimately render the available experimental evidence for increasing mass with increasing velocity, in the final analysis, entirely insufficient and inconclusive.
