question_answer 42)

  Describe the motion of a charged particle in a cyclotron if the frequency of the radio frequency (rf) field were doubled.

Answer:

                  Time period of revolution of charged particle in cyclotron, T = Frequency of revolution,   If = 2, then = = a constant. It means, the charged particle will accelerate and decelerate alternately between the dees of cyclotron. So the radius of path in the dees will remain unchanged.
