Assertion: In the duration electron jumps from fist excited state to ground state in a stationary isolated hydrogen atom, angular momentum of the electron about the nucleus is conserved.
Reason: As the electron jumps from first excited state to ground state, in a hydrogen atom, the electrostatic force on electron is always directed twoards the nucleus.

Answer

D

Explanation

As electron jumps from `n-2` to`n=1`, angular momentum `((nh)/(2pi)) ` does not remain conserved.
