Question

Anode rays produced by isotopes and isobars possess
same charge when taken in different discharge tubes.
Which among the two sets of anode rays show different
deflections in the presence of an electric field?​

Answer 1

$\large\underline\mathfrak\green{♡\:Answer\:♡}$

Anode rays are produced in the discharged tubeon applying a high electrical voltage to the gas which is present in the tube. ... The different gases have different types of positive rays,that contain particles of different mass and charge. Therefore, the charge to mass ratio of anode depends on the gas.
