MCQ
The units of angular momentum are
- A$kg - {m^2}/{s^2}$
- ✓$Joule - s$
- C$Joule/s$
- D$kg - m - {s^2}$
✓
Answer
Correct option: B.
$Joule - s$
b
$=m \vee r W =F \cdot d $
$=m \vee r W =F \cdot d $
$L =[k g][m / s][m] y =m \cdot a \cdot d $
$ L =k g \cdot m^2 s^{-1} =k g\left( m / s ^2\right)$So, Joule-$s$ $=k g \frac{m^2}{s^2} \times s=k g m^2 s^{-1} .$
