Question

Fill in the blanks
If the speed of electron increases, its specific charge _________.

Answer 1

When speed of electron increases the specific charger decreases because with increase in velocity charge remains constant. Another reason is specifice charge is the ratio of the charge to mass. Also we know that specific charge is $\frac{e}{m}$

$\frac{e}{m}$ is inversely proportional to the velocity of the electron and therefore as speed of the electron increases,the specific charge decreases.
