A singly charged ion of unknown mass moves in a circle of radius 13.5 cm in a magnetic field of 2.9 T. The ion was accelerated through a potential difference of 3.0 kV before it entered the magnetic field. What is the mass of the ion? (hint: EPE=Vq=KE)
kg

  • Physics -

    Vq=1/2 m v^2
    v= sqrt 2 Vq/m

    centripetal force=magneticforce
    1/2 m v^2/r= Bqv

    solve for mass.

    solve for m.
