When the speed of electrons increase, then the value of its specific charge

Question

When the speed of electrons increase, then the value of its specific charge (A) increases (B) decreases (C) ramains unchanged (D) increases upto some velocity and then begins to decrease

Tardigrade Admin · Accepted Answer

Here the velocity of electron increases, so as per Einstein's equation mass of the electron increases, hence the specific charge (e/m) decreases.

ramains unchanged

increases upto some velocity and then begins to decrease

Here the velocity of electron increases, so as per Einstein's equation mass of the electron increases, hence the specific charge $\frac{e}{m}$ decreases.
