UV light with a wavelength of 180 nm is incident on a metal and electrons are ejected.
Question:
UV light with a wavelength of 180 nm is incident on a metal and electrons are ejected. Instead of determining the maximum kinetic energy of the electrons with a stopping potential, the maximum kinetic energy is determined by injecting the electrons into a uniform magnetic field that is perpendicular to the velocity of the electrons. For a certain metal, the electrons with maximum kinetic energy follow a path with a radius of 6.7 cm in a magnetic field of 7.5 × 10−5 T.
(a) What is the work function for this metal?
(b) Do electrons with maximum kinetic energy follow a path with the maximum or minimum radius?
