3. In which figure is the box's weight equal to the normal force in magnitude? 4. In which figure is the magnitude of the normal force greater than the weight of the box? 5. Are mass and the gravitational force the only factors that effect to the normal force acting on an object? 6. In which figure (or figures) does the box have an apparent weight different from that caused by its mass and the gravitational field alone?WEIGHT AND NORMAL FORCE FN (a) mg FN 50.0 N (b) + mg 50.0 N FN (c) + mg 0
