In photoelectric effect, the stopping potential $\left(\mathrm{V}_{0}\right) \mathrm{v} / \mathrm{s}$ frequency $(v)$ curve is plotted. (h is the Planck's constant and $\phi_{0}$ is work function of metal)
(A) $V_{0} \nu / S v$ is linear.
(B) The slope of $\mathrm{V}_{0} \mathrm{~V} / \mathrm{s} \nu$ curve $=\frac{\phi_{0}}{\mathrm{~h}}$
(C) $h$ constant is related to the slope of $V_{0} V / S V$ line.
(D) The value of electric charge of electron is not required to determine $h$ using the $\mathrm{V}_{0} \mathrm{~V} / \mathrm{sv}$ curve.
(E) The work function can be estimated without knowing the value of $h$.
