Vedclass · Answer

(C) The velocity of an electron in Bohr's model is given by the relation $V \propto \frac{Z}{n}$.Here,$Z$ is the atomic number (representing the magnitude of positive charge on the nucleus) and $n$ is the principal quantum number.Statement $I$ claims that velocity increases with a decrease in positive charge $(Z)$. However,since $V \propto Z$,the velocity actually decreases as the positive charge on the nucleus decreases. Thus,Statement $I$ is false.Statement $II$ claims that velocity increases with a decrease in the principal quantum number $(n)$. Since $V \propto \frac{1}{n}$,the velocity increases as $n$ decreases. Thus,Statement $II$ is true.
