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