A current carrying loop ABCO, carrying current 4.0 A, dimensions OA = 20 cm and AB =10 cm, is placed as shown in figure. The magnetic moment of the loop is
(1) \((0.07\hat{j}+0.04\hat{k})Am^2\)
(2) \((0.04\hat{j}+0.07\hat{k})Am^2\)
(3) \((0.07\hat{j}-0.04\hat{k})Am^2\)
(4) \((0.04\hat{j}-0.07\hat{k})Am^2\)
