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