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
Options
(a) 1.8 V
(b) 1.2 V
(c) 0.5 V
(d) 2.3 V
Correct Answer:
0.5 V
Explanation:
The stopping potential is equal to maximum kinetic theory.
