Question

What is the relation between angular momentum of an electron with their spin?

• A. $\sqrt{s(s+1)}\frac{h}{2\pi }$
• B. $s(s+1)\frac{h}{2\pi }$
• C. $\frac{h}{2\pi }$
• D. $s(s+1)\frac{2\pi }{h}$

Answer 1

The correct option is A $\sqrt{s(s+1)}\frac{h}{2\pi }$

The spin angular momentum is given by the formula,
$L_{spin}=\sqrt{s(s+1)}\times h/2\pi$.
Similarly, the orbital angular momentum is given by,
$L_{orbital}=\sqrt{l(l+1)}\times h/2\pi$.
