A singly charged ion of 7Li (an isotope of lithium) has a mass of 1.16x10-26 kg . It is accelerated through a potential difference of 230 V and then enters a magnetic field with magnitude 0.703 Tperpendicular to the path of the ion. What is the radius of the ion's path in the magnetic field? Use 1.60x10-19 C for the magnitude of the charge on an electron.
