Photoelectric Effect [ENDORSED]

[Chase Yonamine 1J]

I understand that Dr. Lavelle explained this during lecture, however, I am still a bit confused. Can someone please explain how an electron is able to reach the detector if there is 0 Kinetic energy. Is there an attractive force of some sort?

As Dr. Lavelle explained, this experiment would be done in a vacuum where the detector plate would have a positive charge. This positive charge attracts the electron to the plate thus allowing it to be detected.

An electron has a negative charge. In the experiment diagram in class, the electron would reach the detector because of a positive charge attracting the electrons to it. Because of the attractive force, the electron would be detected without use of kinetic energy.
