The electromagnetic radiation of wavelength 200 nm are incident on a metal plate 'A'. The photo electrons are accelerated by potential difference 10.2eV. These electron strike another metal plate 'B' from which electromagnetic radiation are emitted. The minimum wavelength of the emitted Photons is 100nm. Find the work function of the metal 'A'.
