Assertion : An isolated metal plate emits photoelectrons when first illuminated by
\( \mathrm{P} \) ultraviolet light but then the number of W. photoelectrons emitted per unit time decreases until it stops altogether.
- Reason : As more and more electrons leave the
- plate, its potential increases, decreasing the number of emitted photo electrons and finally stopping them.

(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
