That is, FE = FB. qE = qvB Therefore, V = E/B In the equation E electric is the quantity that is measured. When replacing v in the equation to calculate the ratio q/m.Thomson was a trial measure. Q/m repeatedly by changing the type of metal used to make the cathode polarity. It appears that the ratio of the cathode ray particles that is calculated from the experiment with the same approximate value is 1.76 x 1011 CU lom per kilogram. He therefore concluded that rises out of the cathode ray all the metal particles is particle mass and the same type as. Subsequently be called electrons (electron) It is considered Thompson as a scientist who discovered the electron. In addition, Thomson was a trial measure of the ratio q/m ratio of an ion of hydrogen atom, which is the loss of an electron to hydrogen. Therefore, hydrogen ion's charge is positive. Thomson found that the q/m ratio of the hydrogen ion is approximately equal to 9.7 x 107 CU lom per kilogram. That this value corresponds to the q/m of separation "with the conductor of the Haifa Hotel Valley. At present, it is known that the charge of the electron with the charge of the ion of hydrogen has a value. Therefore, a comparison of the two particles x 1011 1.76 to know more than the mass of the electron, hydrogen ion, there are approximately 1800. Experimental results of Thomson showed negative electrode made of metal of all kinds can provide electrons. Thompson thus concluded that atoms originally understood that it is not broken down. The truth.
