Question

Assertion (A): The potential energy of an electron revolving in any stationary orbit in a hydrogen atom is positive.
Reason (R): The total energy of a charged particle is always positive.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false and Reason (R) is also false.

Hint:

In atomic physics, the total energy of an electron in a hydrogen atom is negative, as it is a bound state.

Answer 1

The Correct Option is D

The potential energy of an electron in any stationary orbit in a hydrogen atom is negative, not positive. The total energy of the electron is negative due to the bound state of the electron in the atom. Hence, both Assertion (A) and Reason (R) are false.
