Question

According to Bohr, the angular momentum of an electron, in any orbit, should be:

• A. $h/2\pi$
• B. $nh/2\pi$
• C. $h/mv$
• D. $2\pi /nh$

Answer 1

The correct option is B $nh/2\pi$

According to Bohr's theory, angular momentum of electrons is quantized. It is an integral multiple of $\frac{h}{2\pi }$.
