A coil of `100` turns and area `2 xx 10^(-2) m^(2)`, pivoted about a vertical diameter in a uniform magnetic field carries a current of `5A`. When the coil is held with its plane in North-South direction, it experiences a torque of `0.3 N//m`. When the plane is in East-West direction the torque is `0.4 Nm`. The value of magnetic induction is (Neglect earth's magnetic field)
