The radiation corresponding to 3→23 \to 23→2 transition of hydrogen atom falls on a metal surface to produce photoelectrons. These electrons are made to enter a magnetic field 3×10−4 T.3 \times {10^{ - 4}}\,T.3×10−4T. If the radius of the larger circular path followed by these electrons is 10.0mm10.0mm10.0mm, the work function of the metal is close to:
