A particle of unknown mass and charge is being used in a cathode ray tube experiment. The magnetic field strength from the coils is 0.434 T. The electric field is created by applying a potential of 3581 V across parallel plates that were set 0.00456 m apart. When the electric field is turned off, the cathode rays are bent into a curve of radius 0.00646 m by the magnetic field. What is the charge to mass ratio for the cathode ray particles
