The period of circular motion

  1. Mar 27, 2009 #1
    1. The problem statement, all variables and given/known data
    Alpha particles (charge= +2e, mass= 6.68*10-27kg) are acclerated in a cyclotron to a final orbit radius of .30 m. THe magnetic field in the cyclotron is .80 T. The period of circular motion is?


    2. Relevant equations

    f=1/T
    F=qvbsin[tex]\alpha[/tex]
    There might be more!



    3. The attempt at a solution

    Welcome to PF.

    Don't you want to consider the effect of centripetal acceleration?

    Won't mv2/R = qv X B yield your velocity and from that you can figure how long to make 1 revolution?
