Which of the following statement is not true about stopping potential (V₀)? (a) It depends upon frequency of the incident light. (b) It is 1/e times the maximum kinetic energy of electrons emitted. (c) It increases with increase in intensity of the incident light. (d) It depends on the nature of emitter material.

Answer: (c). eV₀ = hν - φ: V₀ depends on frequency (a true) and on the emitter's work function (d true). V₀ = Kmax/e (b true). V₀ does not depend on intensity, so (c) is the false statement. So the answer is (c).

Photoelectric Experiment: Intensity, Stopping Potential & Graphs

Which of the following statement is not true about stopping potential $(\mathrm{V}_0)$ ?

Show answer and solution

Answer: (c)

$eV_0 = h\nu - \phi$ : $V_0$ depends on frequency (a true) and on the emitter's work function (d true).
$V_0 = K_{max}/e$ (b true).
$V_0$ does not depend on intensity, so (c) is the false statement.
So the answer is (c).
