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

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.
