A particle of mass $m$ and charge $q$ is accelerated from rest through a potential difference $V$ . The final velocity of the particle is $v$ .

A second particle of mass $m3\frac{m}{3}$ and charge $3 q$ is accelerated from rest through a potential difference $2 V$ .

What is the final velocity of the second particle in terms of $v$ ?
