NEET Physics Stopping Potential MCQ Question
The variation of the stopping potential (V₀) with the frequency (ν) of the incident radiation for four metals A, B, C and D is shown in the figure. For the same frequency of incident radiation producing photo-electrons in all metals, the kinetic energy of photo-electrons will be maximum for metal
A
B
C
D
Correct Answer
Detailed Explanation
The stopping potential is directly related to the kinetic energy of the photo-electrons. The metal with the highest stopping potential will have the maximum kinetic energy.
