Which of the following expression represents the relation between orbital magnetic moment and orbital angular momentum of an electron?

Options

A. `mu_("orb")=-(2m_(e))/(e)L_("orb")`
B. `mu_("orb")=-2m_(e)L_("orb")`
C. `mu_("orb")=-(3)/(2m_(e))L_("orb")`
D. `mu_("orb")=(e)/(2m_(3))L_("orb")`

Answer

C

Explanation

As , `(mu_("orb"))/(L_("orb"))=(-e)/(2m_(e))`
`implies mu_(orb)=(-e)/(2m_(e))L_("orb")`
were , `mu_("orb") `= orbital magnetic momentum
`L_("orb")`=orbital angular momentum
