Dual Nature of Radiation and Matter question

2011 · Q125

NEETPhysicsDual Nature of Radiation and MatterMCQ+4 / −1
In photoelectric emission process from a metal of work function 1.8 eV, the kinetic energy of most energetic electrons is 0.5 eV. The corresponding stopping potential is
  1. A
    1.8 V
  2. B
    1.3 V
  3. C
    0.5 V
  4. D
    2.3 V
View written solutionFree

Correct answer: C

Maximum K.E. = Stopping Potential

So stopping potential will be 0.5 V
