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
A) 1.3 V
B) 0.5 V
C) 2.3 V
D) 1.8 V
Correct Answer:
B
Solution :
Stopping potential = Maximum KE \[eV=K{{E}_{\max }}\] So, option is correct.
