A point source of light is utilized in a photoelectric effect...

The stopping potential in a photoelectric effect experiment is given by Einstein's photoelectric equation:

$eV_0 = h\nu - \Phi$

where $V_0$ is the stopping potential, $\nu$ is the frequency of incident light, and $\Phi$ is the work function of the metal.

When the point source of light is moved farther from the emitting metal, the intensity of light falling on the metal decreases. However, the frequency of the incident light remains unchanged.

Since the stopping potential depends only on the frequency of the incident light and the nature of the material, it is independent of the intensity of light.

Therefore, the stopping potential will remain constant.
