PhysicsSingle correct+4 / -1Question 44 of 75

Angular momentum of an electron in a hydrogen atom is $\dfrac{3h}\pi$ , then the energy of the electron is ________ eV.

-1.51

-0.85

-0.38

-0.28

Answer and worked solution

Official answer: C

Bohr quantisation. $L=\dfrac{nh}{2\pi}=\dfrac{3h}\pi$ , so $n=6$ .

Energy. $E=-\dfrac{13.6}{36}=-0.38$ eV.

(C)

Topics:Bohr model and hydrogen spectrum
