Q. Order of $q/m$ ratio of proton, $\alpha$-particle and electron is
A) $e > p > \alpha$
B) $p > \alpha > e$
C) $e > \alpha > p$
D) None of these
Explanation
(a) $\because m_{e} < m_{p} < m_{\alpha} \Rightarrow \left( \frac{q}{m} \right)_{e} > \left( \frac{q}{m} \right)_{p} > \left( \frac{q}{m} \right)_{\alpha}$
