Physics - Error Question with Solution | TestHub

If f is increased keeping I and work function constant then stopping potential and maximum kinetic energy of photoelectrons increase.

If the distance between cathode and anode is changed then stopping potential remains same.

If I is increased keeping $f$ and work function constant then stopping potential remains same and saturation current increases.

Work function is decreased keeping $f$ and $I$ constant then stopping potential and maximum kinetic energy of photoelectrons increase.
