In this week's experiment, we will accelerate electrons and inject them into magnetic fields generated by Helmholtz coils in the direction perpendicular to the magnetic fields.
(a) If electrons are accelerated from rest through a potential difference of 364 V, what is the final speed of the electrons?
m/s
(b) If the magnitude of the magnetic field is 10.6 Gauss, what is the radius of the electrons' orbit? Answer in unit of cm.
cm
