Vedclass · Answer

(C) According to Bohr's theory,the velocity of an electron in a stationary orbit is given by $v = \frac{2 \pi Z e^2}{n h}$.This expression shows that the velocity $v$ is independent of the mass of the electron $(m_e)$. Thus,doubling the mass does not change the velocity.However,the kinetic energy $(KE)$ of an electron is given by $KE = \frac{1}{2} m_e v^2$.Since $KE \propto m_e$,if the mass of the electron is doubled,the kinetic energy will also double,meaning it increases.
