A proton moves from a location where V- 86 V to a spot where V= -43 V.
(a) What is the change in the proton's kinetic energy?
(b) If we replace the proton with an electron, what is the change in kinetic energy?
If the potential difference is needed to stop an electron is -0.349 V, what was the initial speed of the electron? Answer in m/s
The phenomenon where electrons are emitted from a material when it absorbs electromagnetic waves is called the photoelectric effect. Visible light shines energy on a metal sheet with energy enough for the metal sheet to emit electrons. In order to measure the energy of these electrons, another negatively charged plate (-24.8 V with respect to the metal sheet) is placed in the path of the electrons. The electrons slow down upon contact with the negatively charged plate and stop. What is the initial speed of these electrons?
