A particle of mass $\displaystyle 2$ kg is on a smooth horizontal table and moves in a circular path of radius $\displaystyle 0.6$ m. The height of the table from the ground is $\displaystyle 0.8$ m. If the angular speed of the particle is $\displaystyle 12 \mathrm{rad} \mathrm{s}^{-1}$, the magnitude of its angular momentum about a point on the ground right under the centre of the circle is :
Official answer
(3)
$\displaystyle 14.4 \mathrm{~kg} \mathrm{~m}^2 \mathrm{~s}^{-1}$
