Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason RAssertion A: In photoelectric effect, on increasing the intensity of incident light the stopping potential increases.Reason R: Increase in intensity of light increases the rate of photoelectrons emitted, provided the frequency of incident light is greater than threshold frequency.In the light of the above statements, choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
(4)
