The work functions of Aluminium and Gold are $4.1\ \text{eV}$ and $5.1\ \text{eV}$ respectively. The ratio of the slope of the stopping potential versus frequency plot for Gold to that of Aluminium is
Answer: (C) 1
$V_0=\dfrac he\nu-\dfrac\phi e$: the slope $\dfrac he$ is the same for every metal. Ratio $=1$.
