Question

The specific charge for cathode rays is (A) constant (B) variable (C) depend upon the material of the cathode (D) depend upon the nature of gas in the discharge tube

Tardigrade Admin · Accepted Answer

Specific charge (e/m) for cathode rays is constant as e and m for cathode rays are fixed.

Q. The specific charge for cathode rays is

constant

variable

depend upon the material of the cathode

depend upon the nature of gas in the discharge tube

Specific charge $(e / m)$ for cathode rays is constant as $e$ and $m$ for cathode rays are fixed.
