Question

In photoelectric effect, the stopping potential $$V_0$$ vs frequency $$
u$$ curve is plotted. $$h$$ is the Planck's constant and $$\phi_0$$ is the work function of metal.

(A) $$V_0$$ vs $$
u$$ is linear.

(B) The slope of $$V_0$$ vs $$
u$$ curve is $$\frac{\phi_0}{h}$$.

(C) $$h$$ constant is related to the slope of $$V_0$$ vs $$
u$$ line.

(D) The value of electric charge of electron is not required to determine $$h$$ using the $$V_0$$ vs $$
u$$ curve.

(E) The work function can be estimated without knowing the value of $$h$$.
