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