Question

A point source of light is used in a photoelectric effect. If the source is removed farther from the emitting metal, the stopping potential (A) will increase (B) will decrease (C) will remain constant (D) will either increase or decrease

When the source is moved away from the emitter, intensity of the incident radiation decreases but frequency remains same so there will be no change in the stopping potential. Thus, it remains constant.
