Asingly charged ion of 7li (an isotope of lithium which lost only one electron) has a mass of 1.16 ×10^-26 kg. it is accelerated through a potential difference of 224 v and then enters a magnetic field with magnitude 0.724 t perpendicular to the path of the ion. what is the radius of the ion’s path in the magnetic field? (give your answer in decimal using "mm"(millimeter) as unit)
