a wire of density d and cross sectional area A fors three sides of a square and is free to rotate about one of its horizontal sides.A magnetic field B exists in the vertically upward direction. When a current i is passed through the wire, the system comes to rest at an angle X to the vertical. then the value of X is given by
1.cosX=2Adg/iB
2.cotX=2Adg/iB
3.tanX=Adg/2iB
4.sinX=Adg/2iB
