Question

The magnetic poles of a small cyclotron produce a magnetic field with
magnitude 0.85 T. The poles have a radius of 0.40 m, which is the
maximum radius of the orbits of the accelerated particles.
a) What is the maximum energy to which protons (q = 1.60×10
-19C, m = 1.67×10-27 kg) can be accelerated by this cyclotron? Give your answer in electron volts and in joules.
b) What is the time for one revolution of a proton orbiting at this maximum radius?
c) What would the magnetic field magnitude have to be for the maximum energy to
which a proton can be accelerated to be twice that calculated in part (a)?
d) For B = 0.85 T, what is the maximum energy to which alpha particles (q =
3.20×10-19C, m = 6.65×10-27kg) can be accelerated by this cyclotron? How does
this compare to the maximum energy for protons
