Suppose you want to identify a bunch of particles using mass spectrometer. First, they are ionized with charge q= +1.6e-19 C. Then the particles pass through the velocity selector with a speed v= 6.7e6 m/s and enters a magnetic field B= 1.4 T.

I have a 7 question final exam and all of questions bond to each other. Can you help me solving them? And you need to use the constants on the second image. This is the first one and second one. Please help me 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 . 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 smallest isotope. In order to produce this magnetic field, determine the current and number of turns, radius and other parameters of a solenoid you need. Also show how you will position this solenoid.
