Answer
(i) In order to experience zero force, the conductor should be parallel to the magnetic field i.e., the angle between the length of the conductor and the magnetic field should be zero.
(ii) In order to experience maximum force, the conductor should be kept perpendicular to the magnetic field i.e.,the angle between the length of the conductor and the magnetic field should be 90°.
