A particle of mass \( 2 \mathrm{~kg} \) located at the
\( \mathrm{P} \) position \( (\hat{i}+\hat{j}) \mathrm{m} \) has a velocity

W \( 2(\hat{i}-\hat{j}+\hat{k}) \mathrm{ms}^{-1} \). Its angular momentum along \( z \)-axis in \( \mathrm{kgm}^{2} \mathrm{~s}^{-1} \) is
(1) -8
(2) +8
(3) -4
(4) Zero
