Hello again. I have a final exam and there are 7 questions. I could not do. I asked my first question and I taked its answer. Then I ask you third question . This question is bonded the first question. The mass difference between two isotopes is sometimes just a neutron mass. The spectrometer should separate them very well. For such an isotope combination, the difference in radius should be around 1 cm. That is r2 - r1 = 1 cm. In order to achieve this, choose a magnetic field with a magnitude in Tesla (maximum magnetic field you can obtain from a conventional magnet is around 2.5 T so be far away from this value) and choose the direction also. Then determine the velocity of isotope you need. Last calculate radius r of a Pb-204 smallest isotope. and that is my 4th question below What should be the power of the voltage supply that we will use in velocity selector region?
