網頁Answer (1 of 4): Let's imagine, we have the nucleus of protium and deuterium. They are the two notable isotopes of hydrogen atom. Now your problem is to find the mass difference between these two nucleus. They are same in charge and have the same physical 網頁2016年10月17日 · Let m be the mass of a charge. Then it will experience a centripetal force provided by the magnetic field B ′: m v 2 r = q v B ′ m v = q B ′ r q m = v B ′ r ( 2) Hence we determined the charge to mass ratio of a charge. Now, the stream of particles may contain charged particles with different masses (isotopes).
