Statement I A metallic surface is irradiated by a monochromatic light of frequency v > v0 (the threshold frequency). The maximum kinetic energy and the stopping potential are Kmax and V0, respectively. If the frequency incident on the surface is doubled, both the Kmax and V0 are also doubled. Statement II The maximum kinetic energy and the stopping potential o photo-electrons emitted from a surface are linearly dependent on the frequency of incident light.

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 of 3×10^−4T. If the radius of the largest circular path followed by these electrons is 10.0 mm, the work function of the metal is close to
