Problem

Two different metals A and B give straight-line plots of stopping potential

V_{0}

versus frequency on the same set of axes. The lines cut the

V_{0}

axis (where

\nu=0

) at

-1.60\,\text{V}

for metal A and

-0.50\,\text{V}

for metal B. Calculate the ratio of their work functions

\phi_{\text{A}}:\phi_{\text{B}}
