Two isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 x 10-27 kg

Question

Two isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 x 10-27 kg and 21.59 x 10-27 kg, respectively. These two isotopes are singly ionized (+e) and each is given a speed of 3.602 x 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.4900 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle. Use 1.602 x 10-19 C as the elementary charge and give your answer to four significant figures. http://edugen.wileyplus.com/edugen/courses/crs2216/art/qb/qu/c21/EAT_12353359027340_324389851872786.gif

Explanation / Answer

use the equation r= mv/(qb) Then find the difference between the diameters not the radii
