easy

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

Increases

Decreases

Remains unchanged

Increases upto some velocity and then begins to decrease

Solution

(b) Here the velocity of electron increases, so as per Einstein’s equation mass of the electron increases, hence the specific charge $e \over m$ decreases.
