Circular motion Radii difference between 2 isotopes
Here is the problem:
If I have Ni58 and Ni 60 and I put them through a uniform Electric field and uniform Magnetic field what is the difference between the two radii? I am given the mass of Ni58 (m) and it's charge (+e), however, don't I also need the mass of Ni60. I think I need it to find its radii difference. Is there an assumption I can make to find Ni60's mass?
Answer
Isotopes differ in the number of neutrons, so their masses are different. The names of the isotopes tell you the mass number, so if you are given the mass of one you should be able to compute the mass of the other isotope. Neutrons are electrically neutral, meaning that they don't affect the charge of the isotope. From this information you should be able to use the formula for the cyclotron radius.
