The figure shows the variation of stopping potential $\displaystyle \mathrm{V}_{0}$ with frequency $\displaystyle v$ of incident radiation, for three materials $\displaystyle \mathrm{M}_{1}, \mathrm{M}_{2}$ and $\displaystyle \mathrm{M}_{3}$ with work functions $\displaystyle \phi_{1}, \phi_{2}$ and $\displaystyle \phi_{3}$ respectively. Then :
Official answer
From CBSE’s own marking scheme for this paper.
(C)
$\displaystyle \phi_{3}>\phi_{2}>\phi_{1}$
