In an experiment on photoelectric effect, the separation between emitter and the collector plates is \( 10 \mathrm{~cm} \). Plates are connected through an ammeter without any cell. A Magnetic field B exists parallel to the plates. The work function of the emitter is 2.39 \( \mathrm{eV} \) and the light of wavelengths between \( 400 \mathrm{~nm} \) and \( 600 \mathrm{~nm} \) is incident on it. The minimum value of \( B \) for which the current registered by the ammeter is zero, is \( (x / 10) \times 10^{-5} \mathrm{~T} \). Evaluate \( x \) ? zero Neglect any effect of space charge.
