Photoelectric Experiment: Intensity, Stopping Potential & Graphs

A point source of light is used in a photoelectric effect. If the source is removed farther from the emitting metal, then the stopping potential will

Show answer and solution

Answer: (c)

Moving the source away only lowers intensity ( $I \propto 1/r^2$ ); frequency is the same.
$V_0 = (h\nu - \phi)/e$ is independent of intensity.
So the answer is (c) remain constant.
