Question

(a) $\frac{{m{v^2}}}{R} = qvB$. For proton ${R_p} = \frac{{mv}}{{qB}} = \frac{{\sqrt {2{m_p}E} }}{{qB}}$
and for deutron ${R_d} = \frac{{\sqrt {2{m_d

Vedclass · Accepted Answer

${R_d} = \sqrt 2 \,{R_p}$

Vedclass · Answer

(a) $\frac{{m{v^2}}}{R} = qvB$. For proton ${R_p} = \frac{{mv}}{{qB}} = \frac{{\sqrt {2{m_p}E} }}{{qB}}$
and for deutron ${R_d} = \frac{{\sqrt {2{m_d}E} }}{{qB}}$
$ \Rightarrow \,\;\frac{{{R_d}}}{{{R_p}}} = \sqrt {\frac{{{m_d}}}{{{m_p}}}} = \sqrt 2 \Rightarrow {R_d} = \sqrt 2 {R_p}$
