(B) The specific charge of a particle is defined as the ratio of its charge to its mass,given by $e/m$.According to the theory of relativity,the mass $m$ of a particle moving with velocity $v$ is given by $m = \frac{m_0}{\sqrt{1 - v^2/c^2}}$,where $m_0$ is the rest mass and $c$ is the speed of light.As the speed $v$ of the electron increases,the relativistic mass $m$ increases.Since the charge $e$ remains constant and the mass $m$ increases,the ratio $e/m$ (specific charge) decreases.

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