How far from the entrance will the beams of the different isotope ions end up?

A m spectrometer is designed to separate atoms of carbon to determine the fraction of different isotopes. There are three main isotopes of carbon, with the following mes. The atoms of carbon are singly ionized and enter a m spectrometer with magnetic field B=0.200 T at a speed of 1.50 x 105 m/s. The ions move along a semicircular path and exit through an exit slit.
