Two singly ionized atoms move out of a slit at point *S* in Figure above and into a magnetic field of magnitude *0.100 T* pointing into the page. Each has a speed of *1.00 × 10^6 m/s*. The nucleus of the first atom contains one proton and has a mass of *1.67×10^-27 kg*, whereas the nucleus of the second atom contains a proton and a neutron and has a mass of *3.34×10^-27 kg*. Atoms with the same number

of protons in the nucleus but different masses are called isotopes. The two isotopes

here are hydrogen and deuterium. Find their *distance of separation* when they strike a photographic plate at *P*.
