Question

when the same isotopic gases is taken in two discharge tubes the angle of deflection is found to be different though the strength of external electric field is applied is same. explain

Answer 1

Explanation:

Cathode rays (electron beam or e-beam) are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Julius Plücker and Johann Wilhelm Hittorf,[1] and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode
