A narrow beam of singly-charged carbon ions, moving at a constant velocity of $6.0 \times 10^{4} m s^{- 1,}$ is sent perpendicularly in a rectangular region having uniform magnetic field B = 0.5 T (figure 34-E15). It is found that two beams emerge from the field in the backward direction, the separations from the incident beam being 3.0 cm and 3.5 cm. Identify the isotopes present in the ion beam. Take the mass of an ion = $A (1.6 \times 10^{- 27}) k g,$ where A is the mass number.
