A beam of protons is accelerated through a potential difference of 0.745 kVand then enters a uniform magnetic field traveling perpendicular to the field.
What magnitude of field is needed to bend these protons in a circular arc of diameter 1.74m?
What magnetic field would be needed to produce a path with the same diameter if the particles were electrons having the same speed as the protons?
