WebThomson also placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery −-− minus the mass of each particle was much, much smaller than … WebA "d" quark has a charge of -1/3 and an up has +2/3 which makes the neutron electrically neutral (-1/3+(-1/3)+2/3=0). In beta decay one of the "d"s is converted into a "u" and an electron is emitted in the process alongside an electron-antineutrino. In this way a new particle is created with three quarks: uud which happens to be a proton!
