The maximum kinetic energy of photoelectrons emitted from a surface when photons of energy 6 eV fall on it is 4 eV. Find the stopping potential in volts.

The maximum kinetic energy of photoelectrons emitted from a surface when photons of energy 6eV fall on it is 4eV. The stopping potential is:

Photons of energy 5 eV and incident on a cathode made of a photosensitive plate. The maximum kinetic energy of emitted photoelectrons is 3 eV . When photons of energy 8 eV fall on the same metal plate , the stopping potential of anode plate will be
