# Consequences of changes in photoelectric experiment setup on stopping potential

If we increase the distance between the collector plate and the emitter plate in the setup of the photoelectric experiment, then will there be any change in the stopping potential? (this thought comes into my mind as electric potential is defined as $$V=E\cdot d$$)

Also by making such a change, is the kinetic energy of the electron affected due to more time and distance given for collisions with other electrons which can cause its kinetic energy to be released consequently changing stopping potential?

Note that in the ideal case if we fix the potential between the plates then the electric field, the gradient of the potential, is $$E = V/d$$ and the work done is $$W = F\cdot d = q\cdot E \cdot d$$ so the two $$d$$s cancel and the total work done is the same (moving the plates apart means the electron has to go farther in the force field, but the force is also weaker).
