हिन्दीAccording to Bohr's postulate, the angular momentum (\( m_e v r \)) of an electron in a given stationary state is quantised and is equal to:
Correct answer · Option 2
\( \frac{nh}{2\pi} \)
Explanation
Bohr's quantization condition for angular momentum is \( m_e v r = n \frac{h}{2\pi} \) where \( n = 1, 2, 3, \dots \)
