SUMMARY

The discussion focuses on calculating the exit positions of three carbon isotopes (12^C, 13^C, and 14^C) in a mass spectrometer under a magnetic field of 0.200 T and an initial velocity of 1.50 x 10^5 m/s. The relevant formula used is r = (mv)/qB, where m is the atomic mass, v is the velocity, q is the charge, and B is the magnetic field strength. The atomic masses are 1.99 x 10^-26 kg for 12^C, 2.16 x 10^-26 kg for 13^C, and 2.33 x 10^-26 kg for 14^C. The charge on carbon ions is assumed to be +1 for the calculations.

Homework Statement


There are three main isotopes of carbon, with the following atomic masses:
Atomic Masses
12^C 1.99 x 10^-26 kg
13^C 2.16 x 10^-26 kg
14^C 2.33 x 10^-26 kg

The atoms of carbon are singly ionized and enter a mass spectrometer with magnetic field strength B = 0.200 T at a speed of 1.50 x 10^5 m/s. The ions move along a semicircular path and exit through an exit slit. How far from the entrance will the beams of the different isotope ions end up?

F = q * v * B = mv^2/R

r = (mv)/qB

is there a charge on C?
