Question

(c) $r = \frac{{mv}}{{qB}} \Rightarrow \frac{{{r_\alpha }}}{{{r_p}}} = \frac{{{m_\alpha }}}{{{m_p}}} 	imes \frac{{{q_p}}}{{{q_\alpha }}} = \frac{4}{1

$2:1$

Vedclass · Answer

(c) $r = \frac{{mv}}{{qB}} \Rightarrow \frac{{{r_\alpha }}}{{{r_p}}} = \frac{{{m_\alpha }}}{{{m_p}}} 	imes \frac{{{q_p}}}{{{q_\alpha }}} = \frac{4}{1} 	imes \frac{1}{2} = \frac{2}{1}$
