A charge particle moves along circular path in a uniform magnetic field in a cyclotron. The kinetic energy of the charge particle increases to 4 times its initial value. What will be the ratio of new radius to the original radius of circular path of the charge particle :
Solution
<p>$R = {{mv} \over {Bq}} = {{\sqrt {2mK} } \over {Bq}}$</p>
<p>$\Rightarrow R \propto \sqrt K$</p>
<p>$\Rightarrow$ ratio = 2 : 1</p>
