1.	A point source of light is taken away from the experimental setup of photoelectric effect. For this situation, mark out the correct statement (s).A. Saturation photocurrent decreasesB. Saturation photocurrent increasesC. Stopping potential remains the sameD. Stopping potential increases
Answer» Correct Answer - A::C 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
