# Two nonrelativistic charged particles, X and Y, have identical positive charges of magnitude q but different masses such that m_Y = 4m_X. Both particles are released from rest and accelerated through the same uniform potential difference \(\Delta V\). What is the ratio of the final speed of particle X to the final speed of particle Y, \(\dfrac{v_X}{v_Y}\)?
