H2 Physics · JC 2 · Hard · Deflection of charged beams

A beam of singly charged ions enters a region of uniform magnetic field at right angles and follows circular paths. Ion X has mass

2.0\times10^{-26}\,\text{kg}

and radius of path

0.10\,\text{m}

. Ion Y has the same speed but radius

0.20\,\text{m}

. What is the ratio

q/m

for ion Y compared to ion X?
