A source of light is placed at a distance of 50 cm from a photo cell and the stopping potential is found to be 
. If the distance between the light source and photo cell is made 25 cm, the new stopping potential will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
By changing the position of source of light from photocell, there will be a change in the intensity of light falling on photocell.
As stopping potential is independent of the intensity of the incident light, hence stopping potential remains same i.e.,
