A charged particle moves during a velocity selector at a constant speed in a straight line. The electric field of the velocity selector is 3.80*103 N/C, while the magnetic field is0.360 T. When the electric field is turned off, the charged particle travels on a circular path whose radius is 4.30 cm. discover the charge to mass ratio of the particle.
