Photons with a wavelength of 440 nm illuminate a metal surface. There is also a uniform magnetic field of 25 ?T in the region. Thus, electrons ejected from the metal are bent into circular arcs with radii ranging from essentially zero up to a maximum radius of 24 cm.

a) What is the maximum kinetic energy of electrons ejected from the metal (in eV)?

b) What is the work function of the metal (in eV)?

c) What wavelength of light would result in a maximum radius for the circular arcs of 48 cm?
