Vedclass · Answer

(B) The stopping potential $(V_0)$ is determined by the maximum kinetic energy of the emitted photoelectrons, which depends on the frequency of the incident radiation, not its intensity.According to Einstein's photoelectric equation: $K_{max} = h
u - \Phi_0 = eV_0$.Since the intensity of light only affects the number of photons incident per unit area per unit time (and thus the number of photoelectrons emitted), it does not change the maximum kinetic energy of the individual electrons.Therefore, the stopping potential remains unchanged when the intensity is increased.

If the intensity of incident radiation in a photocell is increased, the stopping potential
