Two short magnets AB and CD in the X-Y plane and are parallel to X- axis and the co-ordinates of their centres respectively are (0,2) and (2,0) . Line joining the North-South poles of CD is opposite to that of AB and lies along the postive X- axis. The resultant field induction due to AB and CD at a point P(2,2) is 100xx10^(-7)T . When the poles of the magnet CD are reversed, the resultant field induction is 50xx10^(-7)T . If the dipole comes to stable equilibrium at an angle of 30^(0) with this field, then ,magnitude of the other field is
