Stopping potential v/s frequency

A photoelectric effect experiment is performed on a certain metal using light sources of different frequencies. The stopping potential $V_0$‍ is measured for each source and plotted against the frequency $\nu$‍ as shown below

Find the work function of the metal.$\begin{array}{rl}& \\ & \end{array}$‍ Note: Take $h=6.6\times {10}^{-34}\text{J s}$‍ and $e=1.6\times {10}^{-19}\text{C}$‍ and round-off your answer to two significant figures.
