A source of light is placed at a distance of 50 ~cm from a photo cells and the stopping potential is found to be V _ 0^* . If the distance between the light source and photo cells is made 25 ~cm , the new stopping potential will be:

Options

  1. AV₀ / 2
  2. BV₀
  3. C4 V₀
  4. D2 V₀

Correct answer

B. V₀

Step-by-step solution

Stopping potential is independent of distance hence new stopping potential will remain unchanged in required. Stopping potential =V₀
