As we've discussed in class, the "normal force" or "perpendicular force" is just a name for the force a surface exerts on an object, in a direction perpendicular to the surface. Suppose you are moving into a new apartment and have to drag a heavy box up a ramp that forms a 30 degree angle relative to the level ground. Which one of the following statements is true about the normal force between the box and the ramp? a. The normal force is less than the weight of the box b. The normal force is equal to the weight of the box c. The normal force is greater than the weight of the box d. The magnitude of the normal force depends on the coefficient of friction between the box and the ramp e. The magnitude of the normal force is zero
