A point source of light is taken away from the experimental setup of photoelectric effect. For this situation, mark out the correct statement (s).

Options

A. Saturation photocurrent decreases
B. Saturation photocurrent increases
C. Stopping potential remains the same
D. Stopping potential increases

Answer

A, C

Explanation

As the source is taken away, the intensitiy of light reaching the target decreases, and hence the photocurrent decreases. But as motion of the source does not affect frequency of light the stopping potential given by `V_0=((hc)/(e))-((phi)/(e))` remains the same
