Hi
Stopping potential will remain constant.
This is because,
When the source of light is moved away from the emitter then although intensity of the incident radiation decreases but frequency remains the same , it means there's no change in the stopping potential as it depends on the frequency and not on the intensity. Thus, it remains constant.
Thankyou
