a. North
b. South
c. East
d. West
e. None of these
3. A .221T magnetic field in a massspectrometer causes an isotope of sodium to move in a circular path with a radius of .06 m. The charge on an ion is 1.60218e-19 C.If the ions are moving with a speed of 19500 m/s, what is the isotope's mass? Answer in kg.
