A circular loop, of radius 20cm, is placed (in the x–y plane), in a uniform magnetic field of strength 2.0 tesla, that is directed as shown, in the xy plane. The loop carries a current 1.0A in the direction shown in figure. The torque acting on the loop will be.
(1) 0.18 \((\hat{i}-\hat{j})\)
(2) 0.18 \((\hat{i}+\hat{j})\)
(3) 0.18 \((\hat{i}+\hat{k})\)
(4) 0.18 \(\hat{k}\)
