An electron is accelerated across an electric field that has a potential dissimilarity of 30 V. After exiting the electric field, the electron enters a magnetic field and is soon to be on a curved path that has a radius gauged to be 6.0 mm. assuming the magnetic field is perpendicular to the path of the electron.
1. What is the magnitude of the magnetic field?
2. What is the frequency of the revolution in Hertz?
