How is the maximum kinetic energy of photoelectrons related to stopping potential V0?
AKmax = V0/e
BKmax = e/V0
CKmax = eV0
DKmax = eV0²
Answer & Solution
Correct answer: C. Kmax = eV0
At the stopping potential even the fastest electron is just halted, so its kinetic energy equals the work done e times V0.
