A magnetic needle of magnetic moment 60 Am^2 is directed towards the geographical north at a place . It experiences a torque of 1.2 x 10^-3 Nm. If the earth’s horizontal component of that place is 40 mu Wb/m^2 then the angle of decimation at that plane will be

if the coil is in the magnetic field of 1.2 T In the above question the field being in the plane of coil then the torque acting on its is
