Thomson experiment e/m
WebThomson also demonstrated the magnetic deflection of cathode rays in a separate experiment. 5. Thomson actually investigated the conductivity of the gas in the tube under varying pressure conditions. See Thomson (1897, pp. 298–300). 6. I shall return to this when I discuss Thomson’s measurement of e/m for the electron. 7. WebAug 7, 2024 · The "fall distance" in a capacitor of length L would be s = 1 2 a t 2 = 1 2 e E m ( L v) 2. From the deflection on the screen s was obtained and from this the charge-to-mass ratio of the electron e m. A description of …

WebJ. J. Thomson, nearly a century ago, successfully measured the charge-to-mass ratio of an electron. Within 20 years Millikan carefully determined the charge of the electron thus enabling its mass to be calculated.
