A charged particle moves through a velocity selector at a constantspeed in a straight line. The electric field of the velocityselector is 3.65x10^3 N/C, while the magnetic field is 0.360 T.When the electric field is turned off, the charged particle travelson a circular path whose radius is 4.00 cm. Find the charge-to-mass ratio of the particle.
