A particle of mass 2 kg is on a smooth horizontal table and moves in a circular path of radius 0.6 m. The height of the table from the ground is 0.8 m. If the angular speed of the particle is $12 \mathrm { rad } \mathrm { s } ^ { - 1 }$, the magnitude of its angular momentum about a point on the ground right under the center of the circle is: (1) $14.4 \mathrm {~kg} \mathrm {~m} ^ { 2 } \mathrm {~s} ^ { - 1 }$ (2) $11.52 \mathrm {~kg} \mathrm {~m} ^ { 2 } \mathrm {~s} ^ { - 1 }$ (3) $20.16 \mathrm {~kg} \mathrm {~m} ^ { 2 } \mathrm {~s} ^ { - 1 }$ (4) $8.64 \mathrm {~kg} \mathrm {~m} ^ { 2 } \mathrm {~s} ^ { - 1 }$
