When the work function of a metal increases, maximum kinetic energy of emitted photoelectrons
- A first decreases and then increases.
- B increases.
- C remains same.
- D decreases.
Answer & Solution
Correct Answer
(D) decreases.
Step-by-step Solution
Detailed explanation
(K.E.) \(_{\max }=h v-w_{0}\)
Hence if \(w_{0}\) increase (K.E.) \(_{\max }\)
Decreases
Hence if \(w_{0}\) increase (K.E.) \(_{\max }\)
Decreases
