Worked Solution & Example Answer:In photoelectricity, $V_s$ is the stopping potential - AQA - A-Level Physics - Question 14 - 2022 - Paper 1
Step 1
What quantity is $eV_s$?
Answer
The equation represents the maximum kinetic energy of a photoelectron released when light of sufficient energy is incident on a material. Here, is the charge of an electron, and is the stopping potential.
Thus, the correct answer is B) maximum kinetic energy of a photoelectron.
