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 :
- AV0/2
- BV0
- C4V0
- D2V0
View written solutionFree
Correct answer: B
Since, stopping potential is independent of distance hence new stopping potential will remain unchanged i.e., new stopping potential = V0.
