MHT CET 2024 Physics question
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
Answer: (C)
Solution
Stopping potential is given by , so it depends only on the frequency of the incident light and the work function of the metal. Moving the source farther away reduces the intensity (number of photons reaching the metal per second), which
