In photoelectric effect, the stopping potential (V0) v/s frequency (v) curve is plotted.
(h is the Planck's constant and ϕ0 is work function of metal)
(A) V0 v/s v is linear
(B) The slope of V0 v/s v curve = \(\frac{\phi_{0}}{\mathrm{~h}}\)
(C) h constant is related to the slope of V0 v/s v line
(D) The value of electric charge of electron is not required to determine h using the V0 v/s v curve.
(E) The work function can be estimated without knowing the value of h.
