NEET 2013 Physics Stopping Potential MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A source of light is placed at a distance of 50 cm from a photo cell and the stopping potential is found to be V₀. If the distance between the light source and photo cell is made 25 cm, the new stopping potential will be:
A
V₀√2
B
V₀
C
2V₀
D
4V₀
Correct Answer
Option B
Detailed Explanation
The stopping potential is independent of the intensity of light and depends only on the frequency of the incident light. Therefore, changing the distance does not affect the stopping potential.
