A particle accelerated by a potential difference enters a velocity selector which consists of perpendicular magnetic and electric fields. The particle travels straight when the magnetic field is 0.400 T and the electric field is 6.30 × 105V/m. Once the electric field is turned off, a sensor determines that the radius or the particle’s path is 4.11 cm.Â
Â
a.   What is the charge-to-mass ratio of this particle?
Â
b. Calculate the charge-to-mass ratio of an alpha particle, electron and proton. Identify the particles used in the experiment from the calculations.  Hint:  check your data booklet for the charges and masses.
