Hello, it says that we must derive m = qB^2r^2/2V ..(volts)

using formula for kinetic energy and E= kq/r^2

thanks in advance for the help

A mass spectometer accelerates ions through a voltage, V, before the ions enter a uniform magnetic field, B, that makes them turn. Develop the forumla m= qB^2r^2/2V for the mass of the ion, using kinetic and charge energy. the radius of the turn is r and the charge is q
