A Source Of Light Is Placed At A Distance Of Physics Question

A source of light is placed at a distance of 50 cm from a photocell and the stopping potential is found to be V₀. If the distance between the light source and photocell is made 25 cm, the new stopping potential will be

Options

(a) 2V₀
(b) V₀ / 2
(c) V₀
(d) 4V₀

Correct Answer:

V₀

Explanation:

Since, stopping potential is independent of distance hence new stopping potential will remain unchanged i.e., new stopping potential = V₀.
