A point source of light is used in a photoelectric effect. If the source is removed farther from the emitting metal, then the stopping potential will
  1. increase.
  2. decrease.
  3. remain constant.
  4. either increase or decrease.

Solution

As the source is removed farther from the emitting metal, the intensity of light will decrease. As stopping potential does not depend on the intensity of light, it will remain constant.
