Photons with energy 5 eV are incident on a cathode C in a photoelectri...

Explanation:

Understanding the Photoelectric Effect:
- When photons of energy are incident on a metal surface, they can eject electrons from the surface, this is known as the photoelectric effect.
- The maximum kinetic energy of the emitted photoelectrons is given by the difference between the energy of incident photons and the work function of the metal.

Given Information:
- Energy of incident photons = 5 eV and 6 eV
- Maximum energy of emitted photoelectrons = 2 eV
- No photoelectrons reach the anode A when 6 eV photons are incident.

Analysis:
- When 5 eV photons are incident, the energy of the emitted photoelectrons can be calculated as 5 eV - Work function.
- Given that the maximum energy of emitted photoelectrons is 2 eV, the work function of the metal is 3 eV.
- When 6 eV photons are incident, the energy of the emitted photoelectrons would be 6 eV - 3 eV = 3 eV.
- In order to prevent the photoelectrons from reaching the anode A, a stopping potential equal to the maximum kinetic energy of the photoelectrons is required. This potential is 3 V.

Therefore, the correct answer is option 'D' (-3 V) as a stopping potential of -3 V relative to the cathode C will prevent the 3 eV photoelectrons from reaching the anode A.
