Question

The angular momentum of a particle of mass $2$ kg moving along a circular path of radius $2$ m with an angular velocity of $2rad{s}^{-1}$ is ____ kg $mrad{s}^{-1}$

• A. $64$
• B. $8$
• C. $32$
• D. $16$

Answer 1

The correct option is D $16$

Given : $m=2kg$ $w=2rad/s$ $r=2m$

So, angular momentum $L=mw{r}^2$

$⟹L=2\times 2^2\times 2=16kgrad/s$
