A charged particle moves through a velocity selector at constant velocity. In the selector, N/C and T. When the electric field is turned off, the charged particle travels in a circular path of radius 3.33 mm. Determine the charge-to-mass ratio of the particle.
Triply charged uranium-235 and uranium-238 ions have masses of kg and kg respectively. The ions are being separated in the 0.250-T magnetic field of a mass spectrometer, where they have a speed of m/s. The ions traverse a semicircle. What is the distance between the ions in the direction perpendicular to the direction of their motion, in the plane of their motion.
What is the magnitude of the applied electric field?
The applied electric field is produced between parallel plates separated by a 1.00 cm distance. What is the potential difference across the plates?
