The radiation corresponding to 3 → 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. If the radius of the larger circular path followed by these electrons is 10.0 mm, the work function of the metal is close to:
