Moving Charge in a Magnetic Field

A charged particle is moving in a uniform magnetic field in a circular path with radius ' $R$ '. When the energy of the particle is doubled, then the new radius will be

Show answer and solution

Answer: (d)

$r = \dfrac{\sqrt{2mK}}{qB} \Rightarrow r \propto \sqrt{K}$
$K' = 2K \Rightarrow r' = \sqrt{2}\,R$
So the answer is (d) $\sqrt{2}R$ .
