Question: The aurora is caused when electrons and protons, moving in the earth�s magnetic field of 5.0ï½105T, collide with molecules of the atmosphere and cause them to glow.
1. What is the frequency of the circular orbit for an electron with speed 1.0ï½106m/s f electron = ?
2. What is the frequency of the circular orbit for a proton with speed 5.0ï½104m/s f proton = ?
