A source of light is placed at a distance of 50 cm from a photo cell and the stopping Potential is found to be `V_0`. If the distance between the light surface and photo cell is made 25 cm, the new stopping potential will be

A

`V_0//2`

B

`V_0`

C

`4V_0`

D

`2V_0`

Text Solution

Verified by Experts

The correct Answer is:
B
Stopping potential is independent of intensity of light and hence independent of distance.
