A particle of mass \( 20 \mathrm{~g} \) is moving with linear velocity \( 5 \hat{i} \mathrm{~m} / \mathrm{s} \) and having position vector
\( \mathrm{P} \) \( (3 \hat{i}+4 \hat{j}) \mathrm{m} \) about origin. The angular momentum
\( \mathrm{W} \) of its particle is:
(1) \( 4 \hat{k} \) Js
(2) \( -4 \hat{k} \) Js
(3) \( -0.4 \hat{k} \mathrm{JS} \)
(4) \( 0.4 \hat{k} \) Js
