The mangnitue of spin angular momentum of electron is givenby :

A

` s= sqrt ( s(s+1) )1/( 2pi)`

B

` s=s h/( 2 pi)`

C

`s=+- 1/2 . h/(2pi)`

D

`s= sqrt((3)/(2) . (h)/(9) 2pi)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
Spong angualr momentum `= sqrt (S(s+ 1)). h/(2pi)`
` s= sqrt (1/2 (1/2 + 1)) . h/(2pi)`
` = (sqrt 3)/2 . h/(2pi)`.
