In a mass spectrometer, a charged particle is first accelerated in an electric field through a potential difference of 1.80 kV. It exits the electric field and enters a uniform magnetic field, perpendicular to the field direction. The magnetic field strength is 0.034 T. The particle is observed to follow a curved path, with a radius of curvature of 2.692 m. (a) Determine the charge to mass ratio of the particle. select units (b) If the particle is a singly charged positive ion, calculate its mass. select units Tolerance = 5%, units mark = 15% Homework is 7 day(s) old, there is no score reduction.
