In a historical experiment to determine Planck’s constant, a metal surface was irradiated with light of different wavelengths. The emitted photoelectron energies were measured by applying a stopping potential. The relevant data for the wavelength (λ) of incident light and the corresponding stopping potential (V0) are given below:
Given that c = 3 x 108 ms-1 and e = 1.6 x 10-19C, Planck’s constant (in units of J s) found from such an experiment is
(A) 6.0 x 10-34
(B) 6.4 x 10-34
(C) 6.6 x 10-34
(D) 6.8 x 10-34
