Question

What is the effect on specific charge if the speed of electron increases?

• A. Decreases
• B. Increases
• C. Remains same
• D. None

Answer 1

The correct option is A Decreases

Specific charge of a particle is ratio of its charge to its mass. Specific charge $=\frac{e}{m}$.
According to the relation between mass and velocity, when velocity increases then mass increases, and specific charge decreases.
