For an electron in the second orbit of hydrogen, the angular momentum as per Boh
For an electron in the second orbit of hydrogen, the angular momentum as per Bohr's model is :
- A. \( \frac{h}{\pi} \)
- B. \( \frac{2 h}{\pi} \)
- C. \( \frac{h}{2 \pi} \)
- D. \( 2 \pi h \)
Step-by-step solution
According to Bohr's model, the angular momentum of an electron in the nth orbit is given by \( mvr = n \cdot \frac{h}{2\pi} \). For the second orbit (n=2), \( mvr = 2 \cdot \frac{h}{2\pi} = \frac{h}{\pi} \).
