Solution

The correct option is D
If both Assertion & Reason are false

Explanation for Assertion :
The maximum kinetic energy of emitted electrons in the photoelectric effect is $1.5 e V$ .
Explanation for Reason :
Electrons in a hydrogen atom must be in one of the allowed energy levels.
If an electron is in the first energy level $n_{1}$ , it must have exactly $- 13.6 e V$ of energy.
If it is in the second energy level $n_{2}$ , it must have $- 3.4 e V$ of energy.
The difference between the $n_{1}$ and $n_{2}$ will be $- 10.2 e V$ .
Here, Assertion & Reason are false.
Hence option D is correct.
