1. Assertion (A): In case of a concave mirror if a point object is moving towards the mirror along its principal axis then its image will always move away from the mirror. Reason (R): In case of reflection (along the principal axis of mirror) object and image always travel in same directions.  
2. Assertion (A): If an object moves in front of a concave mirror parallel to principal axis. The angle between the object velocity and image velocity can never be acute. Reason (R): Object velocity and image velocity perpendicular to principal axis for spherical mirror is not same.
