Question 106 of 200

In photoelectric effect, the stopping potential $\left(\mathrm{V}_0\right) \mathrm{v} / \mathrm{s}$ frequency $(\nu)$ curve is plotted.
( h is the Planck's constant and $\phi_0$ is work function of metal )
(A) $\mathrm{V}_0 \mathrm{v} / \mathrm{s} \nu$ 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 $\mathrm{V}_0 \mathrm{v} / \mathrm{s} \nu$ line.
(D) The value of electric charge of electron is not required to determine $h$ using the $V_0 \mathrm{v} / \mathrm{s} \nu$ curve.
(E) The work function can be estimated without knowing the value of $h$.
