2 metallic plates P(collector) & Q(emitter) are separated by a distance of 0.10m. These r connected through an ammeter without any cell. a magnetic field B exists parallel to the plates. light of wavelengths between 400nm & 60nm falls on the emitter whose work function is 2.39eV. Calculate minimum value of B
such that no current is recorded in the ammeter
